This is just the opposite problem that I have. When I first boot up it seems that everything is slow. I click on the applications tab and it can take 30 seconds before it shows up. I start a desktop app and again it will take 30-50 seconds before it comes up. Once I have run a few apps etc. and things are cached, then the problem seems to go away. Until my memory fills up. Why is Gnome so unresponsive before things are cached. I'm running a 2GHz system with 512Megs of RAM, and 7200 rpm PATA 133 hard drive.
