Performance
Part 4: Advanced settings for the adventurous
Like virtual memory settings, disk cache settings in Windows Vista aren??™t
necessarily optimized for the best performance, but rather for the best compromise
between performance and compatibility with older PCs.
You??™ll probably need to experiment with different values
until you find the ones that work best for your system. Since
it??™s possible to render Windows inoperable with incorrect
settings here, you??™ll want to back up your PC before you
begin.
Start by opening the Registry Editor (described in Chapter 3), and expanding
the branches to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Session Manager\Memory Management. Some of the more interesting values in
this key include the following:
DisablePagingExecutive
Values: 0 = disabled (default), 1 = enabled.
Enabling this setting will prevent Windows from paging certain system
processes to disk, which effectively will keep more of the operating system
in the faster physical memory, in turn making Windows much more
responsive.
