I vaguely remember a thread somewhere that concluded that one of
these network benchmark tools degenerated into a benchmark of
gettimeofday(2), which apparently is very cheap on Linux and not
cheap on OpenBSD. So you end up measuring the performance of this
system call.

I don't remember whether it was iperf...
