Please be careful with the vmstat output. It presents an average over a
longer period of time. I'm not sure what it does precisely. Run "vmstat 2",
ignoring the very first line of numbers. I got this wisdom from the book
named "System Performance Tuning". I highly recommend it to anyone who wants
to tune his or her box.
