Yes, FreeBSD has quite a few limits hardcoded which
gives other OSes a chance to look decent in various
tests and benchmarks.

Anyway, please provide additional details. CPU
load one of the most important factors here. According
to some people, polling makes it show incorrect (lower)
values. Can you run iperf with different switches? Can
you try and tweak polling-related sysctl variables?
