Caching and the page file

[b11_]

Under Wxp, is the page file cached?

 

[David Webb]

The simple answer to your question is yes, since the page file is a cache itself
and blocks of memory are written to it. The general terms "caching" and "cached"
mean to hide or store in a cache.

He asked whether the pagefile itself was cached, not if it was a cache.
Unless one were using third party tools the Windows XP pagefile would
not be cached. Vista can use ReadyBoost to cache portions of the
pagefile but XP has no such abilities.

It's a bit unclear what b11 is up to or what exactly he has in mind, the
question asked is a bit difficult to figure out! As far as I know
without third party tools on Windows XP the only way to cache the
pagefile would be to store it in the file cache, which would pretty well
defeat the purpose of the pagefile to begin with! Maybe he has oodles
of RAM and he wants to store the pagefile in a RamDrive or RamDisk, I
don't know what he is up to. Microsoft has instructions on its site
somewhere on how to create these RamDrives.
