I have read a few articles on how Linux manages memory. The thing I get from it is this, Linux likes to have data in memory first, then it uses swap because it is more "organized". The last place it wants data is on the hard drive. It is all about speed of access. Linux likes to be really fast. I guess if you have 16GBs of ram and it only access say 10GBs of data, then it will eventually have everything in memory and not access the drive much at all. Same can be said for memory plus swap except that swap is on the drive of course. I will say this, I have 1GB of ram on mine. I run a full install of KDE and I have had 100 or more pictures open with Gimp and have never ran out of memory. The most swap I have ever used is about 200MBs and that is with it set to use a lot of swap. I think it was set at 80 or so. With Linux, 1GB is a lot of ram. The only exception being some heavy games or video stuff. If you have it, I would leave it unless you know you need it somewhere else. That's just my opinion and is subject to change.
