modulo differences in the default UDP SO_RCVBUF size (assuming that the
bind code doesn't make a smaller than default on all platforms
setsockopt() call), and modulo differences in acutal path length (which
I would think would appear easily in say netperf UDP_RR tests with CPU
util enabled - although watch those CPU assignments) I would wonder if
maybe there were differences in the interrupt coalescing between the
platforms?
