Points:
(IIRC) generally discard the first line of output, as this is the stats
since last reboot.

As the man pages says, use "vmstat -w 5" to get more "stable" results,
otherwise they may seem to "bounce around" and make it harder to see
the loading of the box.

Hi all,

I'm trying to troubleshoot a OBSD 3.1 running squid on sparc64 (784MB 
RAM with 3x18 scsi HDD). After 2 days, cache response becomes too slow 
and I need to run vmstat too see where the problem lies. First timme 
using vmstat for troubleshooting. Server is supporting 2000 users.

So far, the server responds with this:

procs   memory        page                    disks     faults     cpu
  r b w    avm    fre   flt  re  pi  po  fr  sr sd0 sd1   in    sy   cs 
us sy id

What do I need to look for?
How do I tell if it's good or bad?
How do I correct it?

Thank you.
