I know this is more of a general unix question, but the thread about the last kernel update, and memory usage got me to looking and thinking. Given a system with 2 Gb of memory, and at peak usage, top reports considerably less than the 2 gig amount in use, as well as system monitoring that never shows all available memory used, what would happen if you just turned swap off, and let memory handle things? This machine here, has now crept up to using just under 400mb of swap, yet I've never seen total memory usage above about 1.4gb. I'm a bit leary of just "swapoff" while the machine is running the weather model, as I'd hate to crash things, but I'm just wondering if turning off swap (assuming the system is actually using the disks) would break things or in the best case, speed things up.
