“Remove dll files on release and do not cache them” apparently isn’t even supported on Windows 2000 and above.
This is from http://home.comcast.net/~SupportCD/XPMyths.html
From website (which quotes microsoft) “Adding this Registry Key in Windows 2000 or XP has no effect since this registry key is no longer supported in Microsoft Windows 2000 or later. The Shell automatically unloads a DLL when its usage count is zero, but only after the DLL has not been used for a period of time. This inactive period might be unacceptably long at times, especially when a Shell extension DLL is being debugged. For operating systems prior to Windows 2000, you can shorten the inactive period by adding this registry key.”
Also, “Do no cache drivers kernel files on the hard drive” appears to be useless.
“DisablePagingExecutive applies only to ntoskrnl.exe. It does not apply to win32k.sys (much larger than ntoskrnl.exe!), the pageable portions of other drivers, the paged pool and of course the file system cache. All of which live in kernel address space and are paged to disk. On low memory systems this can force application code to be needlessly paged and reduce performance. If you have more than enough RAM for your workload, yes, this won’t hurt, but then again, if you have more than enough RAM for your workload, the system isn’t paging very much of that stuff anyway. This setting is useful when debugging drivers and generally recommended for use only on servers running a limited well-known set of applications.”
Anyway, anyone has tested whether the optimizations do anything?
Can someone direct me to the exact registry entries that are changed?
