Have you tuned OSX for high RTT paths?

See: http://fasterdata.es.net/host-tuning/osx/

Let me know if that helps.

We’ve been using BWCTL with iperf to test connections to perfSONAR servers across the country (70ms) with terrible results.  I just want to make sure that using BWCTL on a Mac isn’t busted before we invest a lot of time.  On a Linux box we get over 800Mbps.  On the Mac we get 100-200Mbps to the same server.

Thanks,
