Are you using secure smtp as well?  If so, then it would seem all your
slow connections are using encryption which could be slowed down if the
machine is low on resources.  Have you tried temporarily opening up a
non-encrypted pop connection to see if it suffers the same problem?

Also, have you tried using the "top" command to view your resource usage?
