Change monitor VM CPU / MMU for best performance?

People,

I'm about to deploy new features of Windows Server 2008 R2 (Remote Desktop Session Host / RDSH) virtual machines to support 50 + a simultaneous RDP access.

To control the virtual machine CPU / MMU may be a good idea to boost performance?

Here is the setting that I mention that I left by default, but don't know which option to click to enable console vSphere:

MMU.JPG

do I need to restart the virtual machine to change the option greater than the background value or something else?

and also, it's the model of VMhost CPU type:

any kind of comments would be greatly appreciated.

Thank you.

Assuming that AMD - V is enabled in the BIOS of your host, the automatic setting for Windows Server 2008 R2 on your CPU will be AMD - V with IVR.  In most cases, this will give you the best performance.  However, for young LBR is much more expensive with IVR with shadow paging.  If your workload is a TLB buster, you might want to switch to AMD - V with shadow paging.  On the other hand, the page table updates are much more expensive with pagination shadow with IVR.  Thus, even if your workload is a TLB buster, it might be better to use IVR if your workload also has a high frequency of updates of page table.

Binary translation is rarely a victory.  However, there are rare cases, such as the work of Windows XP 32-bit workloads that rub on the TPR, where the binary translation surpasses hardware-assisted virtualization.

The only way to be sure that you have selected the best mode is all benchmarks.

Yes, you don't have to restart the virtual machine to change the execution mode.

    N ° it will not work. Copy your data to the external hard drive, and then make your own install if that's what you want. But take a look at the "slow computer" information below first. Certainly you should backup your data to the external hard drive regularly even when.

The user can also run several real-time antivirus/firewall/security programs.

  • Guidelines for best performance MS SQL server on EQL

    Hello

    Currently, I have a VM that the C: drive of the system as a disk VMDK on a LUN in a table of PS6100XV (24x600GB 15 k SAS drives).
    This logic unit number is shared with other virtual machines.

    The data and logs is on the D: drive which is a MS iSCSI initiator attached volume on the same table of PS6100XV.

    I think to create two volumes on the Bay and move the data and logs to the respective volume. Will this increase performance or it won't make a difference because the table is a part of 24 disks with a pool. What about braces?

    Can I create different pools and put the different volumes on these pools so volumes using different storage arrays which gives best performance? What is the optimal configuration of the eql to host SQL volumes?

    Thank you

    You certainly want to separate EQL volumes for logs and data.   It was a best practice for a long time, with or without virtualization.   The operating system has a queue of SCSI for both of these "readers" since there is in fact only a single drive.

    If you have not already you must configure the EQL MPIO customer volumes and install HIT / ME software, available on the site Web of Equallogic.   That will optimize the I/O of these volumes.

    If you do that a single physical Bay, you can have only one tank.  If you have two arrays of members, you may have one in swimming and one in the other.  There is no way to split a single physical table on more than a pool.

  • Upgrading RAM for best performance with an Intel Celeron 2.20 GHz Core good option?

    Hello
    I have an old laptop with Intel Celeron 2.20 GHz (1 Core only), 2 GB of DDR2 RAM.
    I want to install Windows 7 / 8 with no problems (bad perf, etc.);
    -> with programming compilers, editor of photo/video/audio or other
    related applications to be run (maybe multitasking).

    is it a good idea to update my RAM to a superior?
    I have 2 ram slots, 1 one slot is used (2 GB).

    If it's good, what can recommend you?
    If not, are there other solutions? or just buy a new one?

    for now, I have less budget...
    pls help.

    Thank you

    The better question is whether or not your computer accepts more than 2 GB of memory, and if so, what memory support or accept.  Once you have an answer to this question then you need determine if the additional memory will help.  Which would be determined by looking at the performance of the system in system monitoring tools and watching low available memory and/or high swap file usage.

  • For best performance, I use tweak 'DISABLE PAGING EXECUTIVE'?

    Hello

    make the final installation of my new office station

    with cs5 production premium and victory 7professional

    I7 - 930, 24 GB of ram ddr3 mushkin, 12 hdd (all raptors of k 10)

    (at this point, I'd rather not RAID)

    Basically, everything has its own drive: os, final render, effects, media cache, previews, "scratch disks", etc.

    2 questions:

    (1) with 24 GB of ram can I still a pagefile?

    (currently I have 1 hdd configuration in the SWAP file)

    (2) using the tweak "disable paging Executive" would help performance?

    again, I have more confidence users adobe Googling for answers...

    Thank you

    j

    1. Yes.  ALWAYS have a pagefile.  It may not be necessary a lot with 24 GB of RAM, but your system may crash hard without her, if it is never actually needed.

    2. I wouldn't worry on this subject.  With that much memory, you're not likely to see much difference.  And Win 7 64 manages memory did MUCH better than XP.  So better to let her do a job without being bothered by the user.

    We were all new at one point, so don't worry what you know.  Win 8 is compatible with all previous OS.  It supports C++, and depends on your video card supports DIrectX 9, 10 and 11.

  • Better NUMA or Hyper Threading is for overall performance?

    Let's say I have a 5.1 ESXi host that has 2 quad-core processors with Hyper Threading, for a total of 16 logical processors. If I have a very greedy CPU VM that I want to give 8 vCPUs, it would be preferable to extend on the NUMA nodes, or apply the configuration numa.vcpu.preferHT = TRUE to force the VM to stay on a single NUMA node and use the Hyper Threading instead?

    I am interested in both to get the best performance for this virtual machine while ensuring that the other (much less CPU intensive) virtual machines running on this host didn't get hungry CPU or block this virtual machine to access the CPU.

    You must understand that this 'Core Hyperthreaded' is not true core. It can do only certain things. It is difficult to assess this performance, but I would say in common, you can not get tasks more than ~ 20% of the performance of ht-core (relative to the true core). Sometimes more, othertimes not.

    So if you run CPU tasks (such as video encoding), it is best to let your virtual machine (with 8 vCPU) to use the two pCPUs (4 real cores of each of them), even if you lose a few cycles of CPU per NUMA.

  • Computer laptop specifications for better performance?

    Hello

    I use Edge CC 2014,

    I always saw a 'delay' in certain actions, as when double-clicking to open a symbol, it takes 3 seconds, or zoom in and out takes 0.5 second.

  • How to monitor the CPU, memory and i/o on the system

    Hello..

    Some body help me?...

    1. how to manage the monitoring of the performance of the system and the database during execution of ODI?
    2. how to monitor the CPU, memory and i/o on the system?

    TQ
    balleur

    In an attempt to partially answer your questions:

    1. how to manage the monitoring of the performance of the system and the database during execution of ODI?

    Monitor the performance of the application from a commercial point of view. As transactions per minute, or response time or time elapsed for the key events of the company. Monitor the activity of the material such that the CPU usage is not necessarily linked to the performance of your application. Performance should be measured from top to bottom - business first, then the lower levels until you get finally to computer equipment. Only if you get a problem to the next level - response time is too large, for example - you can go through the lower levels to identify the cause and fix it.

    2. how to monitor the CPU, memory and i/o on the system?

    I personally use "sar" on UNIX-BASED or Linux, or rather "CFDCs" which is the system activity data collector. SADC will measure and collect data on activities on CPU, memory, disks, etc. and save them to a file in binary format. You can then extract these measures later for analysis using SAR (sar f sadc_file_name). The benefits of SADC are that it is light (these operating systems measure such things anyway, just CFDC records far), it records everything at once (with the exception of the network), it records the time stamp too for each measure, and you can analyze it later when you want to.

    There are commercial products out there too who do similar work, with additional features, such as the integration of Oracle and the relationship between several systems. TeamQuest is an example, but there are others also. (I do not work for TeamQuest, but I used their product in the past).

  • What is the best keep the battery in the best performance?

    Is how better consider keeping batteries for laptops in the best performance: 1-supported always. 2 - Use batteries for laptops without plug in power when the battery is charging.

    Hello

    It makes no difference which way you use because if you keep the AC/DC adapter is plugged in and the battery is fully charged, the battery will not be used. It will only be used if you unplug the AC adapter.

    In addition, a battery can be recharged up to 500 times so I always work with connected AC/DC adapter. But I would say to completely load and unload the battery from time to time. ;)

  • iPad 1/2 fix for slow performance (finally!)

    After several years of desperately poor performance of my iPad 2 and original iPad, I finally understand how to behave reasonably well again.

    Before making this "correction" (you don't like it!), even my iPad menus have been slow to react.  After the correction, it rolls again.

    It turns out that native background apps, including Mail, can be incredibly hard on the performance of the iPad.  You wouldn't think that when the mail was not the app it would affect anything - but it makes.

    If you have a lot of emails (read or unread, is not serious), or have a large calendar and your menus are often jerky and the iPad seems to freeze every now and again once, for a few seconds, welcome to your 'solution '.

    Simply remove your accounts email and calendar of the iPad.  Simply access your e-mail via the web browser instead of using the Mail app can be all that it takes to find correct performance on your tablet.

    For maximum performance, you can continue, stripping of the iPad to each native function, you can: turn off notifications, set the background picture to black, disable automatic updates, all and in circles who does something.

    This explains why it's being a zero factory makes the iPad to work well again.  When we reset the iPad, there is no account e-mail attached to the Tablet, and it rolls.  We add our email account, and after a few moments, the Tablet starts download and return of the tablet to poverty once more.

    I was ready to throw both my iPad 1 and 2 by the window, but they are now in full service.

    Hope this helps someone out there.

    Your method of mail is a bit extreme, you may want to try all of my own below the solutions in the futture.

    All my old iPads and older iPads I started day/updated are ongoing enforcement just peachy keen on the last iOS without resorting to NOT use and delete content in the Mail application native iOS.

    In addition, with the native mail app, if you use iMAP, mail actually remains on the mail server. It is not, in fact, get downloaded or stored on an iDevice, himself.

    When you create new folders in iOS App Mail, you, in fact, create folders in your e-mail/s account on the servers of e-mail service. Not on your iDevice.

    The only reason that the Mail app could be the cause of performance problems, it is that you have set mail to automatically extract the mail at a time interval that may be too short and the iDevice is constantly ping servers of e-mail for short mail a few minutes or less.

    I have my Mail application set for manual removal, so my iDevices are not constantly check new email every few minutes or less.

    Also Push mail off if mail out Internet ping the mail server permanently, either.

    You really don't have to do what you did!

    There are other e-mail settings, you need to change.
