Disk cache vs virtual memory in Windows...what's the difference?
Posted on 2004-09-07
Hoping everyone can help set me straight on this subject, because I have often thought these two were the same thing.
This subject was brought up because we're using an app that requires a lot of memory (both physical and virtual).
One of my team members asked if we should re-configure the app to not write so much data out to memory, and let Windows Disk Caching handle the load.
Now, to my knowledge, disk caching occurs when an action is performed repeatedly in windows, and Windows caches the required info for that action to speed things up. Now, isn't that "cache" in virtual memory anyway?
Would really appreciate an assist here, I learned most of the principles of computers off of *nix boxes, and sometimes Windows throws me a curve, so I want to make sure I understand what's going on here.
