XP Prefetcher Information and Tweaks
Windows XP has a service called the Prefetcher. It basically monitors the
different programs that start during startup and helps them launch faster. Very
detailed information can be found
here. "Logical prefetching is accomplished by tracing
frequently accessed pages in supported scenarios and efficiently bringing them
into memory when the scenario is launched again. When a supported scenario is
started, the transition page faults from mapped files are traced, recording
which page of a file is accessed."
train the prefetcher you can tell it specific applications to prefetch. I have
the instructions for doing this right
this tool browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory
important key is EnablePrefetcher. Default value for this SHOULD
1 means to prefetch boot processes only.
2 means prefetch applications only
3 means prefetch both (make sure you're using this)
have a very low amount of RAM you will want to disable prefetching
Set the value to either 0-Disable.
everything else in windows after a while the prefetch ends up with files that
haven't been used in quite a while. Every so often you should browse to
C:/windows/prefetch and clean out what you don't need.
