Well, depending on your OS.  iostat and vmstat both work on Solaris and
FreeBSD.  Only vmstat works on Linux.  sar exists on IRIX, but not the
other two.  (Could be wrong about some of these, I just telneted to all
the systems I have access to and typed the commands.)

Personally I'm a little more spoiled - I like to load up a nice graphical
process watcher like qps (search for it on freshmeat.net if you don't
have it).  It's similar to top, but the information is much more grokable
in one large chunk - the color-coded bars which show swap, memory used
by processes, memory used by cache, free memory, and so forth are a little
clearer.
