[K12OSN] Slow performance

[Mark Gumprecht]

Try a vmstat 5 and check si and so. I believe that those are the swap in 
and swap out. If you are swapping to the drive, find more ram for it (if 
possible), swapping to the drive will KILL your performance. I had 5 
clients running off of a 1.2 ghz with 2 gig of ram and an ata 100 drive 
( can't remember size, it was to play with) and that was right on the edge.
