benchmark

[dworkin]

Release 0.9 comes with a benchmark based on clients sending each other messages.

For Hydra 1.3.40, the benchmark scales up to about 95% on 30 cores, i.e. it is .95 * 30 faster than single-core (tested on AMD Epyc 7502, Linux 6.8.0). Hydra will use n - 2 cores for LPC tasks when n > 8.

The free 32-bit binary only scales up to about 8 cores on the same hardware.

CPUs with higher core count remain to be tested. Note that running under virtualization slows down Hydra significantly.
