Load averages and intepreting process info
If top shows a high load average, how do I see if something unreasonable is happening on my linode or its just that host very busy. In other words, how do I tell if I'm the culprit taking more than my fair share?
If we assume that the bottleneck is disk i/o which Chris's comments suggest it is, then should I look for STAT = D in a ps aux output. If there aren't any, then is it safe to assume that I'm not causing the problem? Are there other things I should look for?

Hey Ross. Do "vmstat 1" and look for high numbers (tens of thousands) under the "si" and "so" columns. That indicates that you're thrashing your swap.
