DON’T BOTHER
The descriptions of these settings contain gross errors. They are best ignored.

DisablePagingExecutive:
This effects only a small portion of the Kernek. If you have. With a reasonable amount of RAM the kernel will hardley ever be paged out anyway.

LargeSystemCache:
As Microsoft clearly states, this is for servers only. For general use it will almost always be a bad thing. It can also cause severe problems with some common hardware configurations.

IOPageLockLimit:
This does absolutely dothing in XP. Support for this setting was removed as of Windows 2000 SP1. It has never been supported on any version of XP or Vista.

Be carefull with the LargeSystemCache switch. If you run a server it is very usefull however if, like myself, you have a gaming machine with lots of memory and use AGP Apature cache this can decrease performance greatly, as Microsoft mentions here:

“When you enable System cache mode on a computer that uses Unified Memory Architecture-based video hardware or AGP, you may experience a severe and random decrease in performance. The Drivers for these components consume a large part of the remaining application memory when they are initialized during startup.”

Otherwise the rest of the suggestions here are great!

Thanks this part was VERY HELPFUL.

3.create a new dword and name it IOPageLockLimit – double click it and set the value in hex – 4000 if you have 128MB of ram or set it to 10000 if you have 256MB set it to 40000 if you have more than 512MB of ram -this tweak will speed up your disckcache
