Hi,

2.5.68 is much smoother, quite less swap is used, my editors are not
pulled out of the swap all the time:

$ free
             total       used       free     shared    buffers     cached
Mem:        515848     505804      10044          0      92808     173876
-/+ buffers/cache:     239120     276728
Swap:       524624      35612     489012

Linux version 2.5.68 (root@jackson) (gcc version 3.2.2) #2 Sun May 4 00:20:13 CEST 2003

20:39:52 up 1 day, 20:17,  2 users,  load average: 3.31, 3.36, 3.19
