        What then would be a good tool to use to check on performance? vmstat?
What would one be looking for? Is there a better tool?
        My measly Celery 400 w/256 meg RAM (directs 2.2gig of traffic/1.2
million file downloads between 8am and 7pm daily) has the following
vmstat output:

   procs                      memory    swap          io     system
cpu
 r  b  w   swpd   free   buff  cache  si  so    bi    bo   in    cs  us
sy  id
 0  0  0      0 152652  19596  35160   0   0     0     0    4     4   0
0   9

I am not sure quite how to interpret the system catagory.. but hey, I am
willing to learn!
