About 60 MB/sec on one end of the disk, more on the other end of the disk. Did you try realtime monitoring your network interface? # route -n get <remoteip> interface: <yourinterface> # netstat -I <yourinterface> -w 1 Do you see errors on the interface? # netstat -I <yourinterface> Another trick to eliminate disk io from the equation is to use nc: machine1 <freebsd>: # nc -o -l 2000 > /dev/null machine2: # dd if=/dev/zero bs=1M count=50 | nc machine1 2000 -Corey Smith
