Try checking out the book Absolute BSD from Michael Lucas.

You can find a link to the sample Chapter regarding system performance here 
at http://www.absolutebsd.com

I've found the rest of the book to be rather good as well.  But if nothing 
else, that sample chapter alone should give you a pretty good idea of what's 
going on.

Hope this helps.

I recently became responsible for our mail server, and lately, the load
average on the thing has been running consistently high, in mid-20's to
mid-30's.  And at the same time, sendmail has become extremely sluggish
in terms of responding to connections on port 25.

There's got to be a bottleneck somewhere, but my experience leaves me
ill-equipped to seek it out.

What procedures would folks recommend for me to follow in order to try and
determine the problem?

Thank you,

john"
