How busy was the CPU and disk?

I don't know enough about the design yet to know about throttling, but
the Nagios FAQ says that multiple copies of Nagios can run in one
machine if certain files are separate.  So if one copy isn't saturating
the machine, you might be able to run multiple "distributed" copies in
one machine.

Next we'll hear from someone who knows better why that is not a good
idea.
