No prob!  Hopefully learned some more about performance tuning while you were at it!

And now I'm going to admit to feeling like a blooming idiot.

As it turns out, the problem was the performance data gathering. We had
three separate performance gathering pieces going at once, and I didn't
know it (I apologize, I started a week ago, and this was the first project,
been learning what I was handed since then).

NDO, pnp4nagios, and perfdata options in nagios.cfg.

I turned all of them off, and suddenly my system is running the checks
with less than 1s of latency (versus the 90+ I was seeing before, and that
was at best).

I apologize, as I feel like I've wasted a bit of everybody's time. It
wasn't deliberate, and I really did go crazy on doing my research
beforehand. I just didn't catch what this bottleneck was until after I'd
bothered you.
