I tested the 2 k max peers and 1 kHz polling rate config with fewer
clients, here are the results:
100 clients - 5% cpu
200 clients - 8% cpu
500 clients - 22% cpu

Testing with reliable data requires changes to the source code, so
I'll skip that for now. It's not a separate benchmarking program, I
just run my server and throw a lot of clients on it. In other words,
each test scenario requires rewrite and recompile so it's a bit of
work to get comprehensive data.
