This is maybe too general a question, but how do I look at vmstat
output to gather trends in performance on a box? What are the areas to
pay attention to and what are the rules of thumb for deciding whats
going on?

Also what are the good performance tuning books covering Solaris 8-10
running on the Sparc platform?
