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.
