One thought on “Easy Way to Adjust LargeSystemCache

    As Microsoft has clearly stated, this setting is for systems used primarily as servers. It is not intended for systems used for other purposes and will generally impair performance. The setting tells WIndows that memory for the system cache has priority over memory for application use. On a file server this is a good thing as application performance is secondary in these systems. But on a workstation this can severly impair application performance.

    Microsoft has tested this setting extensively.

    This setting can be dangerous when used with some common hardware configurations. It creates an environment that many hardware devices and drivers were not designed for and they react very badly. It is deadly with some common video cards and other devices. Problems range from severe performcance hits, system instability, and data corruption. Some users have been forced to reinstall Windows to restore operation.


    Anyone considering this setting should carefully research the implications and possible risks.
