But, it's really looking like the problem is simply that Linux is using up too much system RAM with cache, resulting in unecessary swap usage.
That is, I think what's happening is it's getting within about 5MB of my total RAM (which is probably far too low, considering the RAM is almost certainly highly fragmented...), and when UT's RAM requirements change a bit mid-game, I get massive stalls.
After reexamining the memory usage, though, I should have plenty. It would be nice if I could find a variable that I could modify to reduce the amount of RAM that the cache will attempt to use, and see if that fixes the stuttering problems.
the cache does not make you swap. LINUX is smart. if it needs ram it will wipe something from the cache. if you have less than 12 megs in swap then there is no problem ( or if you do you just have verry little ram), Linux can be run on 4 megs of ram.
Linux has great memery managment.
If you dont want your computer using swap, then turn swap off! via editing the fstab. I know many ppl that have 512+ megs ram that dont use swap, i use swap because i am often working with files 1 gig +
