Silly as it might seem when did you last recompile the iperf port? I was
about to post a me too post yesterday, until I updated my system to use
the latest sched_ule at which point iperf froze my system completely,
recompiling the port fixed the freeze and the <100Mbit/sec on localhost.
I think it was compiled against the wrong threading library (been a
while since i last recompiled it.)

However i am seeing a gradual increase of speed the more i run it,
caching of some type i assume.
