Quick Tip–The Registry.

Wednesday, March 28, 2012

imageTrying to eek out every last drop of performance on your Windows server?  Chopping things down from the registry is a great place to start.  Aaron Silber has sent over a bunch and here’s another.  Leveraging this on Citrix Servers could improve performance (certainly won’t hurt).

Disable random driver verification
The driver verifier at random intervals verifies drivers for debugging. Disabling this functionality might improve system performance. For many high-throughput systems, every CPU cycle counts. Disable random driver verification with the following registry entry:

Key:                                                HKLM\SYSTEM\CurrentControlSet\Control\FileSystem
Value:                                            DontVerifyRandomDrivers
Data Type:                                   REG_DWORD
Range:                                           0 – 1
Default value:                              0
Recommended value:                1
Value exists by default?            No, needs to be added.
