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.
