Interpreting Vmstat for problems

Hi All

Please give me your input on these vmstat I/O numbers.

I would like to know your thoughts on these statistics, and how you recommend interpreting them:

The ones I am concerned with are:

wa: IO-wait time. Time spent waiting for IO
r: The number of processes waiting for run time.

This is a 2.6 kernel, 1.3ghz machine with and ide drive and 1 gig ram running * and hylafax, ha linux on a T1.

Appreciate your thoughts,

Basically the very first and very last number are the ones I am not too clear about. Can this affect asterisk?
