• slow performance with CentOS 5.5 reviews and multiple vCPUs

  We installed a server in CentOS 5.5 postgresql database comments in vSphere 4.

  This prompt 'verik' (2 vCpu, 16 GB RAM, core EAP) is the only host running on the vSphere host (2 x 6 core AMD Opteron 2439SE, 128 GB of RAM).

  We are witnessing very low yield (for example, when executing a pg_dumpall). The CSTP % seems rather high, especially compared to % RUN - and surprising since there is no claim to the resources of the host.

  We tried a variety of 2.6.18 kernels EAP (including attempts with the CONFIG_HZ 100 and with a divider = 10 options). More or less consistently poor performance.

  The BIOS of the host settings are:

  HyperTransport technology: HT 3

  Assist HT: enabled

  Virtualization technology: enabled

  DRAM prefetcher: enabled

  Training Software Prefetch Prefetch material: enabled

  Hardware prefetcher: enabled

  Demand-based power management: disabled

  We have also tried to run this comments with 1 vCPU (2.6.18 - 194.8.1.el5PAE):

  The first run after a reboot:

  time pg_dumpall >/dev/null

  Real 8m1.764s

  user 0m12.649s

  sys 0m3.133s

  While it works, the system fails (for example, a 'top' which should be updated every second can be updated every 7 seconds). The guest spends a lot of time in the 'system', do what we do not know.

  CPU: 17.3%us, 81.9%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.8%si, 0.0%st

  It takes 7 minutes on a server physics multi-core (4x2.8Ghz Xeon).

  It takes 17 minutes at best (more time) on "verik" with 2 vCPUs.

  We would really like to migrate our physical postgres server in VMware, but we cannot justify it doing so unless he can perform at least as well as on physical hardware. (We tried to store the database on the local disk and mounting NFS host datastore; similar performance in all cases. We also checked adequate bandwidth on our links for storage and front networks.)

  We reviewed several postings on execution of the guests with more than 1 vCpu and think we understand how vSphere CPU coscheduling works. But in our scenario, without conflict of use of CPU resources, we do not know why we're having performance issues.

  Any suggestions?

  Thank you!

  First, why OS 32-bit VMS with 16 GB of RAM?

  My first and very strong suggestion is to go for the 64-bit version of CentOS, EAP is known to have poor performance. Run us multiple virtual CentOS 64-bit machines, and I can't say that we have unexplained performance issues.

  You might try to twist a little bit the 32 bit existing OS, but I don't expect a big improvement. Keep this divider = 10 in your kernel parameters, but if you like to try again with simple CPU add 'nosmp noapic nolapic' kernel parameters, those can drop the percentage of time processor rdy one quite a bit, at least I saw that happen on busy ESX host. Also assign some pages of huge memory in the Linux kernel and configure PostgreSQL to use.

  Your BIOS settings also appear to be inefficient, the General recommendation is to disable the CPU features on the ESX host preloading since when the CPU executes several processes (VMs) preload results in a high number of failures which is just waste of cycles CPU.

  Equipment training on Software Prefetch Prefetch: disabled

  Hardware Prefetcher: disabled

  But still, go for 64-bit operating system.

• Poor ESXi 4 NFS Datastore Performance with various NAS systems

  Hello!

  In testing, I found that I get between a half and a quarter of the e/s inside a guest performance when ESXi 4 systems connect to the using NFS data store if the clients connect to the exact same NFS share.  However, I don't see this effect if the data store using iSCSI or local storage.  This has been reproduced with different systems running ESXi 4 and NAS systems.

  My test is very simple.  I created naked CentOS 5.4 minimum installation (completely updated 07/04/2010) with VMware Tools loaded and the creation time of a file of 256 MB using jj.  I create the file on the root (a VMDK stored in different data warehouses) partition or a directory of the NAS mounted via NFS, directly in the comments

  My crucial test configuration consists of a single test PC (Intel 3.0 GHz Core 2 Duo E8400 CPU with a single Intel 82567LM-3 Gigabit NC and 4 GB RAM) running ESXi 4 connected to a printer HP Procurve 1810 - 24 G, which is connected to a VIA EPIA M700 NAS system running OpenFiler 2.3 with two 1.5 to 7200 tr / MIN SATA disks configured in front of software RAID 1 and dual Gigabit Ethernet NIC.  However, I have reproduced it with different ESXi PC and NAS systems.

  This is a release of one of the tests.  In this case, the VMDK is a store of data stored on the NAS via NFS:

  The first dd is a VMDK stored in a connected via NFS data store.  The dd ends almost immediately, but the synchronization takes nearly 40 seconds!  It's less than 7 MB per second transfer rate: very slow.  Then I get the exact same NFS share that ESXi is used to store data directly in the comments and repeat the DD.  As you can see, the SD is longer and the synchronization takes no real time (as befits a NFS share with active sync), and the whole process takes less than 10 seconds: this is four times faster!

  I don't see these results on data warehouses mounted via NFS.  For example, here is a test on the guest even running from a mounted via iSCSI data store (using the exact same SIN):

  As you can see, the performance of NFS direct comments for each of the three are very consistent.  ISCSI and the performance of the store local data disk are both a bit better than that - as I expect.  But the mounted via NFS data store gets only a fraction of the perfomance of the any of them.  Obviously, something is wrong.

  I was able to reproduce this effect with an Iomega Ix4 - 200 d as well.  The difference is not as dramatic, butalways important and consistent.  Here is a test of a guest of CentOS using a VMDK stored in a data store provided by an Ix4 - 200 d via NFS:-.

  Once more, the direct NFS mount gives very consistent results.  But using the diskette provided by ESXi on a mounted NFS datastore gives still worse results.  They are not as terrible as OpenFiler test results, but they are constantly between 60% and 100% longer.

  Why is this?  What I've read, NFS performace is supposed to be within a few percent of the iSCSI performance, and yet I see between 60% and 400% worse performance.  And this isn't a case of the SIN is not able to provide correct NFS performance.  When I connect to the NAS via NFS directly inside the guest, I see much better than when ESXi connects to the same NAS (the same proportion!) via NFS.

  The configuration of ESXi (network and network cards) is 100% stock.  There is no VLAN in place, etc., and ESXi system has only one

  Single Gigabit adapter.  It is certainly not optimal, but it doesn't seem to me to be able to explain why a virtualized guest is able to get a lot better performance NFS as ESXi itself to the same NAS.  After all, they both use the same exact suboptimal network configuration...

  Thank you very much for your help.  I would be grateful any idea or advice, you might be able to give me.

  Hi all

  It is very definitely a performance O_Sync problem. It is well known that NFS VMware shops still use O_Sync for writes little matter what share put for a default value. VMware uses a custom file locking system so you really can't compare it to a normal NFS share connection to a different NFS client.

  I have validated that the performance will be good if you have an SSD cache or storage target with enough reliable battery backup.

• Question about Lab Manager and ESX Resource Pools

  Hello world

  I was wondering if I can get feedback from some of the members of the community.  We used Lab Manager very strongly in our support organizations and it has proved to be a valuable tool.  Recently, we collaborated with the Department of technical training and started hosting online seminars and classes for them using Lab Manager.  Last week we had a fairly large class of users (approx. 45), each duty deploy 2 rather Beefy VMs that were very intensive resources (Jboss, SQL, Mail to name a few).  My colleague and I went through a lot of trials and planning to ensure that our infrastructure can handle the load while allowing our users to date at the same speed and reliability, so that they are used.

  Our Lab Manager ESX server pools made up of the following:

  5 HP DL380 G5 servers with 2 x Quad Core 2.8 GHZ processors (8 cores each) with 32 GB of RAM each

  2 HP DL580 G5 servers with 4 x Quad Core 2.8 GHZ processors (16 cores each) with 128 GB of RAM each

  When the class is running and everyone has made their 2 machines, we noticed for some reason, he was all on ESX2 and 3 deployment (380 s).  Then came the ESX alarms, use of 90% of memory, then more than 100% bringing the disk page.  The CPU usage was at a all time high.

  I look at the 2 580 s and there are about 4 virtual machines deployed on them.

  So my question is...

  How does he know where to launch a Virtual Lab Manager machine?  There's no sense 2 servers have been brought to the red zone, and almost overloaded when the 2 most powerful servers in my farm are nearly dormant.  I noticed sometimes in the past, but not this bad.  Normally, we have about 45-50 computers deployed at some point and it seems to spread them out properly.

  This group of training has access to the same LUN and ESX server with Betclick as any other organization that we have.

  We have decided hosting several sessions of training may be greater than this one and would like to know that the virtual machines will be distributed properly.

  I would like to know your opinion on this

  First to answer your question, then make guess what happens.

  As indicated in response Ilya, LM distributed VMs differently with active DRS resource pools and pools of resources without active DRS.

  LM place VMs when the DRS is not used.

  When DRS is used, we use the DRS admission control to select the host to place virtual machines.

  DRS is turned off, LM uses its own placement routine:

  For each virtual machine, LM filter all managed servers that cannot run the virtual machine. A complete list of patterns are:

  • The managed server has not enough memory or quota for virtual machine to run the virtual machine.

  • The host is not connected to the data store that is the virtual machine.

  • The virtual machine has active state (suspended) and the CPU of the server managed by the waking state has been captured is not compatible with the managed server currently considered.

  • The virtual machine has been a guest on 64-bit and the managed server is not 64-bit capable.

  • The virtual machine has more processors than the managed server.

  • The managed server is not accessible or is set to "prohibit deployments." Not reachable may mean that the lm-agent or its not to ping queries is not answer (this is visible in the list of managed server page).

  Once we have the complete list of eligible servers, we place the virtual machines on the host including the smallest (MemoryReservation % + CPUReservation %). By default, we reserve not CPU on LM VMs, this internship will be largely due to the memory on the host computers if you have not changed the settings of reservation of CPU on your virtual machines.

  For closed deploy to the PF3, force us all virtual machines to go on the same host, so if any virtual machines have any special data store / CPU type specification, all virtual machines is forced to go on this host. If there are conflicting requirements between different virtual machines in the same configuration, deployment will fail. Closed VMs also have another condition to check that is rarely achieved in practice: number of closed networks available on the managed server. By default, this is 20 and you will need more than 20 different configurations closed running on a managed server before you who will strike.  (LM4 allows Cross fencing host, so this does not apply in LM4).

  To make a guess blind because of your distribution problem - if you use the saved state and fencing, it's probably the type of processor.  Processor type can be checked on the host properties page.

  If you not are not I would check that the images can deploy on the 580 s by disabling the 380s and trying to deploy them.

  If you use DRS (which you're not), it could be due to deployment of virtual machines too fast for the algorithm of control for the entrance of VC.  An easy solution for this is to extinguish the DRS on the cluster manager of laboratory.

  We tested load internal repeatedly, the product QA in different laboratories, we run (LM has been used in VMworld Labs for the past couple years and internal systems of training and demonstration for our Organization implemented SE), so no need to worry about this.  I assure you that the first 'real' performance problem you will encounter will be almost certainly due to an overload of your storage array (too many IOPS / s)... and for that you have to distribute content in data warehouses and use techniques of creating paths to balance the load.

  Kind regards

• Openfiler and vsphere 4.0 and esx 3.5. possible?

  Hi all

  I with openfiler iscsi san using vmware workstation 6.5 method and worked well.  I wonder if you can install the virtual machine within vsphere 4.0 and esx 3.5 openfiler and create the 80 GB drive and make iscsi san.  Anyone know if this work.  I tried the same method with vmware workstation 6.5 and did not work.  Help me please.

  If it is essentially a test environment POC, it should be fine, but using VMware workstation 6.5 method would be good enough for then why try you this method?  You can use other appliances virtual network of Lefthand, target iSCSI rocket Division, Xtravirt VSA, etc... Or, I place openfiler VM on a laptop or a cheap PC and run as your NFS/iSCSI solution.

  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

  Only the PC engine can do directly co-simulation with Simulink. You cannot use a MDL file directly on a target of RT. This type of co-simulation is certainly not in real time and is not suitable to run on an RT target that performs other urgent tasks. You can have multiple targets in your system definition, then you might have an RT target and a target PC. But you need means of communication between the two target types.

  How to use transfer windows for xp to xp.  When I plug usb computers are delivered to the top with the same screen and when I try to use the transfer to the new computer, it just said information gathering and sits for hours

  Hello, welcome.

  The process is automatic and the maximum transfer rate should be about 20 GB/HR. If the process crashes during that long of a time, it's probably because of something internal rather something you're doing wrong.
  For reference purposes, I included this link. It goes into the details of the migration from XP to Vista (and the basic steps you follow). The instructions are for migrating to Vista via the network, but you can easily follow the steps and choose a different option for your specific installation.
  http://www.windowsnetworking.com/articles_tutorials/migrating-Vista-using-Windows-easy-transfer.html
  For both machines, I recommend you to prepare for the transfer using the following procedure:
  1. click on START > run

  2 type "msconfig" (without the quotes) and press enter

  3. go to the "Startup" tab and uncheck all the entries displayed

  4. click on 'Apply' at the bottom right

  5. click on START > run

  6. Type "cmd" (without the quotes). Right-click on the result at the top of the menu START and select 'run as administrator '.

  7. type chkdsk /r and press enter

  8 allow the system to attempt disassembly of the volume

  9. allow the system to plan restarting

  10. restart your computer

  11 let checkdisk analyze the file system on your hard drive

  12. Once completed, perform the same steps on the other machine

  13. Once completed, repeat the transfer

  
  Let us know what happens

  Page file space: 7.07 GB
  File: E:\pagefile.sys

  Right click on 'my computer' and selecting 'Properties' shows exact needs to be visible to a 32 bit OS... 3.24 GB of RAM. So, how MSINFO32. EXE is able to detect all of 8 GB is totally beyond me. But this isn't my problem.

  My BIG PROBLEM is the virtual memory. If I open the root of my drive E:\, it shows the swap file to size: 4 096 MB. And that's how it is in 'my computer' > 'Advanced' > 'Performance' > 'Advanced' > 'virtual memory' > 'change'.
  Custom size:
  -Initial size (MB): 4096
  -Maximum size (MB): 4096
  Total size of file for all readers:
  -Minimum authorized: 2 MB
  -Recommended: 4978 MB
  -Currently allocated: 4080 MB

  Why is-MSINFO32. EXE, statement my total virtual memory 2 GB and the size of pagefile 7.07 GB? Neither is correct! Can someone explain just what the heck happens here? My research on Google, many other people report the same total/available virtual memory amounts, with wildly different hardware configurations. I changed the size manually and rebooted several times, without result. I had the pagefile, sitting in a 5 GB partition, and then he moved on to another drive with plenty of space and assign "System managed". Divergence still existed.

  The material is as follows:
  [|] ASUS M4A88TD-V EVO/USB3 BIOS v1702 [|] AMD PhenomII x 4 (970 Black Edition) [|] Corsair CMZ8GX3M2A1600C8 (x 2) mode modules together ~ 800 Mhz & calendar 8-8-8-24 [|] Integrated graphics card Radeon HD 4250 with 128 MB + 512 MB memory [|] ASUS VE248H 24 "1080 p HD LED monitor [|] Drives from Maxtor 6V250F0 (x 4) 250 GB SATAII 1.5 Gbps [|] LG BD - DL Optical Drive WH10LS30 [|] Creative Labs X - Fi Platinum Sound Card [|] Logitech LX 700 keyboard/mouse wireless [|]

  I changed the speed / "timing" on the RAM to run ~ 666 Mhz @ 9-9-9-24, and the problem persists. As far as I know, he is not actually detrimental to the system; that is, it does not regularly, crash or anything. But the fact that MSINFO32. EXE cannot obtain such a right basis is VERY disturbing for me. There is no state what operating system says it is, then what fundamental problem may arise at some point in the future? Or is already there, hidden and wait a moment when the system load is high until it rears its ugly head and denounces all?
  I wonder if I should completely eliminate virtual memory? Or at least reduce the pagefile to 2 GB or close? After all, I can't imagine many running programs as long as 3.24 GB (RAM available for the operating system) is not sufficient to contain all this. I guess only he pourrait happen, however, is why I'm reluctant to totally renounce virtual memory.

  Anyway. Responses of all appreciated. Gimme a solutionand I will give my first-born. Or at least the neighbors...

  Hi VesanusTempestatum,

  Your question is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for the IT Pro TechNet public. Please ask your question in the following forum.

• MCBUILDER. EXE running rampant, competing with updates for CPU and possibly associated with an update failed chess SP2 and the backup and restore

  Running Vista Home Premium SP1 and the system has been slow and freezing. MCbuilder appear to be using 50 to 100% of CPU, and it is a process that seems no way of killing. I disabled in Services, but again, it seems to start without any particular reason and hinders attempts to install programs or updates vista hogging resources. This can be associated with a problem that has arisen since June because I am not able to perform backups or set restore points (gives the error "0 x 81000101 the creation of a shadow copy has timed out"). I tried to install SP2 in the hope that it will not solve the problem, but the failure of installation and install KB947821 doesn't seem to work either. As the restoration of the system is defective, I would be grateful for the pointers to the resolve or completely remove this mcbuilder problem.

  You have COMODO or AVG Antii-virus installed on your system?  It is known problems with these two programs and MCbuilder.exe.  I don't have Microsoft Resource Builder Cache as a service in the Services (so I can't activate or deactivate it)-you which version of Vista to help (bit, SP-number version)?  I have 32 bit Vista Business SP2. I see no way to turn it off in order to close it with the Task Manager when it is - with the exception, but who could become annoying if it happens frequently and with multiple instances.  I could find nothing useful in Knowledge Base Microsoft on it hogging resources although I've seen a few threads using Bing (which is where I came up with COMODO and AVG anti-virus conflicts).

  You can be infected by malware (which may be the origin of the program to activate and run "without reason"). While in Test Mode safe mode (press F8 during startup and select mode safe mode with networking repeatedly) to run anti-malware programs. To resolve this problem (if it is a problem) download, install, and run the following two programs: http://www.malwarebytes.org/mbam.php and http://www.safer-networking.org/en/index.html.  You can also try a free trial of Pandasoft (www.pandasoft.com).  Before you download pandasoft, uninstall all anti-virus program you currently use (because the installation and execution of two simultaneously can cause conflicts, freezes and all sorts of problems).  Once you have uninstalled your current AV program, download, install, update and scan using Pandasoft.  I think you might be amazed at how much she notes that other software missed.  Once complete, uninstall pandasoft and re - install your current AV program (unless you decide to spend that I did when I tried about 4 years ago).  You can also try the new, free Microsoft Security Essentials http://www.microsoft.com/security_essentials/default.aspx (with the same caveat that only program AV one ALONE can be installed and running on your system at any time). Restart after finishing all the scans and see if the problem has been resolved.

  Try a system restore to a point in time BEFORE the problem started (which can be a problem if it began all the way back in June - you should have posted here then when this process would probably have worked).  Here is the procedure: http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/.  Don't forget to check the box to show more than 5 days of restore points (but I doubt that you will have a pretty far back and forth to the system restore may not be a viable option).  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re - install any software and updates that you have installed between now and the restore point, but you can use Windows Update for updates.

  If the system restore does not work, do a startup repair, boot from the disk Installation of Windows Vista genuine (or one that you can borrow from someone) or a recovery disc.  Here is the procedure: http://www.bleepingcomputer.com/tutorials/tutorial148.html.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.

  If you do not have a floppy disk, you can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD.

  If this does not work, try to start in safe mode (repeatedly hit F8 key so that the start and go in safe mode with networking).  Then we will check some of your system files:

  Go to start / all programs / accessories / command prompt and right click on command prompt, and then click Run as administrator.

  Type sfc/scannow, go and let it run.  It will scan and try to correct some of your system files.  If all goes well it will complete with no corruption, he couldn't fix it (if there is such corrouption post here or try to analyze it to find the problem or files using http://support.microsoft.com/kb/928228.  I bet there is something involving the program or associated with this program.

  If this does not work, you will need to do a repair/system upgrade using the Windows Vista Installation disc authentic (you own or that you can borrow from someone).  Here is the procedure: http://www.vistax64.com/tutorials/88236-repair-install-vista.html as well as the upgrade from an earlier version of the Windows section of the following: http://support.microsoft.com/kb/918884.  Although this will not affect your data, settings or programs, you should always back up your data before you start just be on the safe side.

  I hope one of these procedures can solve your problem (probably the SFC command or controls anti-virus).  If this isn't the case, after return and we will try something else.  Return message anyway so we know how it turns out.

  BTW, for update of the problems you are having with SP2, post on the Forum of Windows Update to: http://social.answers.microsoft.com/Forums/en-US/vistawu/threads where the people who specialize in update issues will be happy to help you with your concerns and get SP2 running on your system (perhaps despite this particular problem).  As you say, it can even solve the problem - who knows.

  Good luck!

• LaserJet P1102w: Laserjet P1102w too slow with MAC OS x and Android

  Hello

  I use the P1102w via WI - Fi for a few months.

  I find it very effective use of Windows.

  BUT it's amazing slowly by any other OS.

  And I use 99% MAC OSX (El capitan).

  Perhaps because there is not a specific driver for MAC? Only the OS Win has a specific program/driver which works very well

  With my MAC OSX (no specific diver HP for MAC OSX on the HP site, instruction to use the MAC drivers) when I send a spool the P1102w printing, it can take 10/05/30 minutes to print a few pages (4).

  Even from between the 1st and the second page printing, it can take some minutes!

  I tried the size and format of different files.

  But even with the small file (less then 1 MB), it's the same result.

  OS Android, it's the same effect. You send the print job, and we must wait and hope that it will work.

  HOPE, because often the print job does not complete successfully.

  BUT the same file of Windows (since a slower PC, my MAC laptop has a better material and performance) has no problem printing and it is sent to the printer in a few seconds.

  Thanks for any suggestion to make MAC & Android printing faster (at least at a speed of accetable, because more than 10 min then for a small print job is not acceptable).

  Hello @Ric_,.

• Very slow performance with Windows 7 on i7 Quad

  I bought my wife a Lenovo E530 i7 quad with screen 1600 x 900 and running Win 7 in September 2012. Previously, she had an Asus Core 2 Duo also with Win 7. The laptop is used to picture (scanning, editing, cataloging) work, family, the navigation and email history.

  The E530 was desperately slow at the beginning. Not better, not faster than the Asus. Performance seems to vary from slow to excruciatingly slow.

  Features include:

  -very slow to open programs

  -slow to react to the choice of menus and clicks

  -slow to react to the touchpad

  -scrolling is not smooth, vibrates, much worse than Asus

  -often distorts the sound and video, audio stutters

  -IE9 make often video has properly - green band across the bottom with the rest of the colors shifted upward - change the video quality will fix it sometimes

  -very slow internet response compared to the other machines on the same network of navigation.

  However, startup speed seems to be OK.

  I spent weeks (months?) through the forums, verification of updates, deletion and restoration of various programs and drivers looking for driver clashes. I tried the clean boot with only Windows drivers and various other combinations, and it made no difference.

  For a long time wifi would be max 54 Mbps but somewhere through the process he begins to operate at up to 300Mbps.

  Nothing seems to stand out in reports on health of the system and the event viewer. Windows experience scores seem to be everything I expected from my older i7.

  Resources and performance monitor reports a problem with the hard drive:

  The average disk queue length = Max 16 = 106

  %Idle = 0

  Disk read/s Ave = 0.093 Max = 3

  Disk sec/Transfer Ave = 0,067 Max = 1

  Disk s/write = 0.022 Ave

  Even when the computer runs slower the CPU usage, and memory usage is not mounted and ceiling ever.

  SFC report any breach of integrity.

  FixIt MS - slow performance does not detect any problems.

  The disk check is not a problem any.

  It's so frustrating that my wife threatens to throw it in the trash and buy a Mac (the horrors :-)).

  Any ideas on what I might have missed or what I should look at?

  Thank you

  Ken

  Wish I had a 128 GB SSD. I suppose you see a serious helping hand to the performance of the system.
