Even on a bare metal system, we are probably already seeing a
significant impact from various meltdown/spectre mitigations, which
are known to be expensive on older hardware.  What matters for this
particular benchmark is whether the line for the highest core count
is straight, and if not, where it bends.

Your system already performed honourably in the configuration that
would be used for a real deployment of Hydra.  What I need at this
point is really tests on more modern CPUs, including non-Intel CPUs.
