I won't pretend to understand how OpenBSD calculates its load averages, but keep in mind that not every OS calculates them the same.
For instance, my OpenBSD box: $ uptime 11:46AM up 3 days, 18:29, 1 user, load averages: 0.08, 0.08, 0.08 I have a .08 load average and there are no services other than sshd and pf running. If your performance isn't taking a hit, don't worry about it.
