Has anyone looked into the impact of port randomization on this benchmark.
If it is generating lots of sockets quickly there could be an impact:
* port randomization causes available port space to get filled non-uniformly
and what was once a linear scan may have to walk over existing ports.
(This could be improved by a hint bitmap)

* port randomization adds at least one modulus operation per socket
creation. This could be optimized by using a loop instead.
