It doesn't matter. They're not tied in that manner.

Did you just change this or is this what it was?

This is all good. You don't have a lot of services at all. How
frequently are you sending results? On my own systems I'm easily
processing at least 13 results/sec. I know that there are others doing
more but there is some point at which nagios can't keep up.

Are there other problems with the machine? Disk or memory issues? Do you
have embedded perl or performance data processing enabled?
