I've recently noticed that the pagefile usage on my Latitude D620 with the Windows XP operating system keeps increasing the longer I leave my computer on. Eventually it gets so large like to 1.3 gigabytes so that things run significantly slower. It increases gradually even though I close applications after I used them, so the problem is not just that I have too many applications open. Of course, I can always restart my computer and the pagefile usage returns to 0.4 gigabytes or so. But restarting my computer is kind of annoying when I am the middle of something. So, I wanted to know whether there is a way to keep the pagefile usage low. I don't see any reason why there shouldn't be. I mean I don't see any reason why the pagefile usage needs to keep growing the longer you leave your computer on. It just seems like the operating system isn't garbage collecting or something.
