ok, i pushed that change public (disabling the automatic buffer resize). 
I was able to run the benchmark at full rate on the macintosh-mini, and 
despite the smaller buffer (whatever the default is) the performance 
seems good.

I tried to set the socket buffer size limit to 50 MB with sysctl -w 
kern.ipc.maxsockbuf but it wouldnt let me go over 5 MB (with a Result 
too large error). Any macox/freebsd experts out there with an idea?

Thanks,
