Virtual Machine tweaks for a better performance

IT Posted on Thu, February 12, 2015 14:19:28

Over the last couple of months I gathered the following tweaks for a better performance insight the virtual machine, besides disabling / uninstalling useless services and devices:

– Disable the pre-logon screensaver:

Open Regedit

HKEY_USERS\.DEFAULT\Control Panel\Desktop

Change the value of “ScreenSaveActive” to 0.

– Disable updates of the last access time attribute for your NTFS filesystem, especially for i/o intensive vm’s this is a real boost:

Open CMD

fsutil behavior set disablelastaccess 1

– Disable all visual effects:

Properties on your desktop

Appearance -> Effects

Disable all options.

– Disable mouse pointer shadow:

Control Panel -> Mouse

Click on the tab “pointers” and switch “enable pointer shadow” off.

– Uninstall Tablet PC Components, unless this feature is needed.

– Disable IPv6, unless it is needed.

– Use the File System Utility (fsutil) command to disable the setting that keeps track of the last time a file was accessed.

For example: fsutil behavior set disablelastaccess 1

– Start the Registry Editor (regedit.exe) and change the TimeOutValue REG_DWORD in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Disk to0x000000be(190).

– Shut down the guest operating system and power off the virtual machine.

Change the virtual machine video card RAM setting to 128 MB.

Power on the virtual machine.
