I'm looking for some hints on evaluating load average. I have a new
system that is showing load averages over .50 most of the time, but I
don't see that it is doing much according to systat vmstat. I figured
that this machine would be way overpowered for the job it is doing.
Is load average (like what is displayed in uptime) really a good
indicator?
What tips do people have for profiling?
