    Speed up through the registry


    I got this from a newsletter (lockergnome) that I subscribe to. Before i try it out I would like to know if this is at all feasible.

    Any comments etc?

    Second level Datacache(L2Cache) is very important for the performance of your CPU. Normally, winXP should recognize your CPU and the value of the L2Cache. However, sometimes XP can't do this, so you must tweak it by yourself to improve the performance:

    run "regedit";
    goto "[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\SecondLevelDataCache";
    modify its value by decimalism:
    AMD Duron: 64(kb);
    PII mobile/PIII E(EB)/P4/AMD K6-3/AMD THUNDERBird/Cyrix III:256;
    AMD K6-2/PII/PIII katmai/AMD Athlon:512;
    PII Xeon/PIII Xeon:1024;

    Increase Speed By Tweaking Prefetcher Settings

    This is a unique technique for XP, which could improve the performance significantly by tweaking the prefetcher. Recommended hardware: PIII 800 or higher, 512M RAM or more.

    run "regedit";
    goto [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnablePrefetcher];
    Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is recommended).

    It will decrease the boot time, but double and increase the performance of your XP. Try it!

    Clean Your Prefetch To Improve Performance

    This is an unique technique for WinXP. We know that it is necessary to wash registry and TEMP files for Win9X/ME/2000 periodically. Prefetch is a new and very useful technique in Windows XP. However, after using XP some time, the prefetch directory can get full of junk and obsolete links in the Prefetch catalog, which can slow down your computer notably. My suggestion is:

    open C(system drive):/windows/prefetch;
    delete those junk and obsolete files;

    It is recommended that you do this every month.

    Highly doubt this is going to have any effect on a remotely modern machine as I think XP is likely to detect the processor correctly (if its something common) and Prefetch seems to be set to 3 by default, so not really much use....
