I was working on my registery trying to speed up my PC when I ran accross this tweak found on the tweaking section of this website. I cant find this in my registry...Any ideas why its not there or what I can do to get it..Thanks in advance....

Diskcache plays a very important role in WinXP. However, the default I/O pagefile setting of XP is conservative, which limits the performance.

Some better values for different RAM are given below.

1. Run "regedit";

2. Goto [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\IoPageLockLimit];

3. Modify the value in Hex depending on the size of your RAM:

RAM: modified value(Hex)

64M: 1000;

128M: 4000;

256M: 10000;

512M or more: 40000.

4. Reboot

Everything else is there in the Memory Management folder except IoPageLockLimit..Any Ideas?

If it's not there you can easily create it but that's not the real issue here.

Read the relevant section here.

Regedit tweaks actually don't do all that much to your system performance. If it's not an option that you can find in a menu, then chances are it won't make any change.
