RE: stress testing

Henry,

Sar is a better tool than vmstat/iostat as it collects a broad range of information. Specifically, sar -q should show up CPU queueing and swapping, and sar -v will show up file/process table overflow issues that may occur during stress testing. IMHO, sar is quite underutilized.... ( had a paper on this last IOUG, but couldn't go and present it :(
