There could be some extra load with the setup/tear down of ssh
connections, but I figure the logrotate's don't happen that often.

Is that 8-10 your load average, or % cpu utilization?  If the latter, it
doesn't sound that bad.  One thing to also consider is that hitting the
webserver a lot can drive up your load.  Especially since every CGI has
to parse/load your entire configuration plus the status of all your
services.  With as many services as you have, I imagine that can be
quite a hit.
