Performance tweak

[Bob]

Searching for performance tweaks I saw the following on systems with more
than 512mb ram.........

Open regedit and go to...

..HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management

DisablePagingExecutive - Double click it to open it. In the decimal
value field, put a 1. This lets XP keep data in memory instead of paging
to the hard drive.

LargeSystemCache - Double click it and change the decimal value to a 1.
This will allow the XP Kernel to Run in RAM.

Create a new DWORD value and name it IOPageLockLimit - Double click it
and set the value in hex to 40000 if you have more than 512MB of RAM.


Will it work and has anyone tried it?

Thanks
Bob

Go here: http://www.x-setup.net/ and download X-Setup Pro. You will find
many tweaks, including the one you asked about, with an explanation of what
they are and why you should do whatever it recommends.

Don't on any normal system. XP will manage what (if anything) it pages
out better if left alone. And the Kernel will normally run in RAM
anyway. This sounds to be ill digested advice. See my page

IOpageLockLimit is bogus, it doesn't do anything (used to, but no more).

The others work, but you can get at them via other GUI methods. Bottom
line: they won't make much of an obvious difference.

there are THOUSANDS of tweaks out there, always be careful applying any of
them, and take good notes, so yo can undo them!

FWIW, you SHOULD get/peruse the TweakUI tool (everyone should):

but, take notes!!!!
