Hello,

Can anyone point me to a tutorial or documentation on how to evaluate
a system's performance using vmstat/iostat/etc. Specifically, what
are pages paged in/out, page reclaims, the `free list', and how
do I tell if my system is requiring more RAM/faster disk bus/etc based
on these values. For instance, is it normal to see a value of 200 under
`pi', but 0 under `po'? What are page faults, anyway (something to do
about a request for memory which is swapped out?)

Please email me, since I'm not on this list.

Thanks,

--dave
