If you have for example a system with only has about 128megs of
RAM. The Windows XP Prefetch can take a lot of this up by
preloading programs at boot as well as preloading programs you
often use thus sucking away your available RAM.
For example: on a system, a Pentium III 800 with 128 megs of
RAM, it was able to greatly boast a system performance by disabling
Prefetch all together. It used for example a half hour for the disk
to stop thrashing after stopping Norton Speed Disk, Now it stops
instantly.
Note: This tweak worked in this example with a system
configuration as described above, but disabling Prefetch on other
systems may have a bad effect as it might free up ram but it also
could increase program start up time.
Here's how to disable Prefetch.
- To open the Registry Editor click on the Start button on
your taskbar, then click on Run and type "regedit"
and click on OK to start the utility.
- Expand
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management\PrefetchParameters\EnablePrefetcher
(see picture 2).
