I just noticed: > Mem: 255948k av, 250540k used, 5408k free, 0k shrd, 28344k buff > 59512k active, 119096k inactive > Swap: 514072k av, 144k used, 513928k free 122280k So if you add X and kde (and other heavy stuff to that), you basically have no RAM, so probably all the slowdown is from constant swapping. Just run top when you see the interactive slowdown and look at the swapin/swapout ratio and swap isage in top & /proc/stat Bye, Oleg
