Slow disks after Cluster creation

Hello

My apologies if this isn't the right place for this question, but I didn't know where to put...

I have a SP1 in Windows Server 2008R2 cluster, composed of two virtual servers VMWare (5.1 ESXi), who knows the drive performance very slow (~10mb/s when copying to or from the cluster disks). If I remove the cluster and put the disks online on a stand-alone server, I can get more than 200 MB/s. The disks are presented as RDM, with two nodes on separate ESX hosts and disks in physical compatibility mode.

Could someone explain why the performance of the drive could become so poor as soon as the cluster is created? All the tests in the last cluster validation report.

Not sure if this helps, but I also noticed that when I turn on maintenance for each of the disks in the Cluster Manager with failover, their performance improves significantly.

Thank you

Hello

First go through the guide of best practices for MSCS by VMware. Come check... If you are using Round Robin for RDM, then this could be the performance issue.

  • GarageBand too slow disk or system overload

    Hey all,.

    Awhile back I posted this same problem and never had an acceptable answer or solution.  No other threads on this topic have contributed to the other.  For about 6 months now, I get this error message in Garageband reading projects.  The activity monitor shows a lot of free RAM and while GB uses 30% of the CPU, I have nothing else running, and therefore to have 60% of CPU still free.  I do not use an excessive amount of plugins, or even the tracks.  I tried to minimize the software titles, but even that seems to have no effect.  In the most recent case, I have only a race.

    To start with, here are my system specs:

    Mid-2012 15 "MacBook Pro

    OS 10.11.2 El Capitan

    GarageBand 10.1.0

    500 GB hard drive (200 GB free)

    2.3 GHz i7 processor

    8 GB 1600 RAM MHzDDR3

    I bought this computer with Snow Leopard and 4 GB of RAM and the latest version of Garageband.  I could play the tracks on the slopes and the use of plugins and never had this problem - never ONCE until the BONES and the GB have been upgraded.  Does anyone have new solutions for this?

    I have the same problem. He arrived only after an automatic update of the GB. Apple monitors this forum, that this message had no response in 3 days? GarageBand is now effectively useless for me.

    I have a macbook pro and have an audio backing track and track a guitar running, which stops after 10 seconds saying too slow disk etc. No other programs are running. The same file ran fine before the update of GB.

    Please help Apple!

  • Problem with XNET start VI after the creation of sessions

    I have a timed loop sending CAN messages via XNET screws. It works great, but I always lose the very first message. It matters little, I send the first message immediately after you create the XNET session or after a few milliseconds.

    The attached screenshot shows the initialization of my four sessions XNET. Although I am starting before the session with an XNET start VI, there is without success to get the first message.

    It seems that the sessions/CAN (selectable cards and HS CAN) interfaces are initialized only after the first call to write XNET. XNET write seems to imply XNET start (see documentation), but the appellant XNET start manually after the creation of sessions does not help.

    What I'm missing to get the interfaces online and ready before you send anything?

    I was able to solve this problem because they did not actually XNET screw sorry for this post.

  • High CPU use/Slow Performance after you install the updates of Windows

    I run Vista Business 32-bit.

    After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

    More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

    Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

    Help!  Thank you!!

    McAfee applications (and Norton) are known for not not upgrade (or uninstalling) itself.

    1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. now run this triple McAfee fix: http://service.mcafee.com/FAQDocument.aspx?id=TS100507

    NOTE: Step #2 McAfee fix run the removal tool, you have already downloaded in my step #1 above.

    4 IMPORTANT! => After the reinstallation of the McAfee application (step #3 of the McAfee fix), manually & repeatedly updated the McAfee application, until you get a prompt "no update more".

    5. open Internet Explorer (only) to http://support.microsoft.com/kb/923737 & run the difficulty.

    6. OPTIONAL: For good measure, pen also Internet Explore (only) to http://support.microsoft.com/kb/971058 & race that secure it in DEFAULT and modes and AGGRESSIVE. [1]

    7 restart a last time & test.

    ~~~~~~~~~~~~~~~~~~~~~~~~
    [1] full Disclosure: the difficulty operating in AGGRESSIVE mode will remove your update history but not the list of installed updates.

  • Why my PC slow down after loading of Norton Internet security 2012

    Windows Search

    Why my PC slow down after loading of Norton Internet security 2012

    Because Norton is a Devourer of resources. I would say deleting and using a user-friendly program over Windows.
     
    Norton and McAfee are the two least friendly Windows security and swine resource to start programs. My ISP offers the McAfee security suite for free and I refuse to use it.
     
    I used to use Avast in conjunction with Windows Defender, (still a decent option), but since MSE became of age, I have used which. MSE is an anti-virus, Anti-Spyware and Anti-Malware program all in one. IMO, it is a program MS got it wrong. And all of these options are freeware.
     
    If you choose to give it a try, download and save the MSE. Remove Norton and install MSE.

    You have a hard drive partition to do - but you would need to contact/see the FAQ from the hardware manufacturer (HP, Dell, Gateway, Lenovo, etc) to see if and how.

    Otherwise - you might have to order (pay for possibly) the factory restore/recovery of the value of the manufacturer.

  • SATA using more slow disks for FRA and archivelogs

    1. I am looking for some advice on staging on a SAN storage for my oracle database. I currently have a San with all SAS 15 K drives and I'm looking to develop the San and add SATA 7.2 K disks store. I want to locate our FRA including our "disk to disk" backup oracle and our archive of these disks SATA 7.2 logs and I was wondering if any effect it would have on our production database?

    2. also, I also plan to place an instance of development entirely on the 7.2 K drives and I was wondering what to expect for performance in this regard?

    Thank you

    Oracle cannot know the details ( t - it? ), but it can occupy.  If your slower disks cannot archive logs fast enough because, well, they are slower, and you have other things going on over there, in the worst case, it could stall your db.  I hope that you would have enough newspapers of recovery to avoid this, but if all goes by one controller, you can still have a problem.  And then, if your system is linked to the CPU, it can make no difference at all.  But if being cpu bound to the means available to it to wait for the processor to perform queries of e/s, it could.  Difficult to say without testing, huh?  in any case, with a San, number of batteries often makes more of a difference than the speed controller and the buffering, buffering, network problems, and so on all are potential bottlenecks or has.  And bottlenecks that make the difference.

  • a notification is sent after the creation of the VM to a specific group does In addition, an end date can be specified in the creation of the VM at the time of its creation?

    (2) during the creation of VM., can an end date being specified with regard to long the virtual machine would be required for?

    Hello

    There are two of them:

    (1) use the workflow of "notification" of the library-> just Mail and build a group (comma seperated or e-mail, Distributor)

    (2) you can program it or build a timer on hold until the date is reached

  • Extremely slow performance after recovery disk restore.

    Machine: Dell portable computer. Router: Netgear. Cable modem: Ubee. OS: Windows 7 Professional Pro. Usage: homepage.  Background: download software WiFi of Mrs Webb Page. When I tried to reboot the system has been compromised and would only boot from the recovery disc after a complete restoration of the self made restore disc. Made several attempts to recover from internal disk using restore without success points.  These recovery discs were made in two years when the system was purchased and loaded. Problem: System is now extremely slow requiring min to access internet and min more than to get to yahoo mail and min more to call individual emails. Browse online or offline is painful causing a lot of pain. Assume total ignorance when you answer the question that follows: HELP?

    If the system is really slow on its own without worrying about all things Internet that I'd work on that to know first since you said "Browse online or offline is painful."

    Dell made a lot of laptops to do so that we can see what you have:

    Click on the button/ORB start in the lower left corner of your screen. Or, press the button of your keyboard Windows logo.

    In the type box:

    Msinfo32

    Select / click msinfo32.exe and the system information dialog box opens.

    Click System summary, click on edit, select all (Ctrl-A), copy (Ctrl-C) and then paste (Ctrl-V) the information back here in your next reply.

    For information about video drivers, expand components, click view, click on edit, select all (Ctrl-A), copy (Ctrl-C) and paste (Ctrl-V) feedback here.

    For the Canadian Techtdo this:

    Expand components, storage, click on disks, click on edit, select all (Ctrl-A), copy (Ctrl-C) and paste (Ctrl-V) the information back here.

    There will be some personal information (such as the user name and the name of the system), and anything that turns information private for you, simply delete the pasted information.

    Sooner or later, it would be nice to have a list of your startup items so while you wait to do this:

    Download and install the free version of CCleaner here:

    http://www.Piriform.com/CCleaner

    CCleaner will want to install an additional startup item in your configuration (that you need not) on the first Setup screen remember to choose to customize the installation and make it look like this, then install CCLeaner:

    CCleaner allows you to manage most of the startup items and also do some other operations oriented cleaning.  Some people will you recommend is not to use the registry functions in CCleaner to avoid these features for now.  I have no problem with it for me, but sometimes it's a contentious issue, I prefer to avoid as much as possible!

    You can uninstall CCleaner later if you don't like it.

    Run CCleaner and choose Tools, boot and bottom right, click on the button "Save to text file" to save the startup information in a text file on your desktop with a name you remember - something like startup.txt

    Save the text file startup information to your desktop (or somewhere you can find it) open the text file with an editor (Notepad or WordPad) and select all (Ctrl-A), copy text, all the text selected in the Windows Clipboard (Ctrl + C) then paste (Ctrl + V) the contents of the startup list of back here in your next reply.
