I have never tuned my oses before. How does one go about finding where
the bottlenecks are? Are there any good resources you can recommend? I
haven't started investigating this yet, but will look later when I
have some time.

I should point out the obvious info I forgot. This particular test
server is running NetBSD 10.1
4 cores of an Intel E5-2680 v4
8 gigs of ram
It has a 10 Gbit shared port, using vioif0
I'm not sure what hard drive is, but it's 50 Gig and shows up as Qemu.
It's also no more than 250 miles from where I live and am testing from.
