It has been suggested that I move this thread to freebsd-stable. The thread so far (deficient NFS performance in FreeBSD 8): http://lists.freebsd.org/pipermail/freebsd-hackers/2011-January/034006.html I updated my kernel to FreeBSD 8.2-PRERELEASE. This improved my throughput, but still not to the level I got from 7.3-STABLE. Here's an updated table from my original message: Observed bytes per second (dd if=filename of=/dev/null bs=65536): Source machine: mattapan scollay sullivan Destination machine: wonderland/7.3-STABLE 870K 5.2M 1.8M wonderland/8.1-STABLE 496K 690K 420K wonderland/8.2-PRERELEASE 800K 1.2M 447K Furthermore, I was still able to induce the NFS "server not responding" message with 8.2-PRERELEASE. So I applied the patch from Rick Macklem. The throughput did not change, but I haven't seen the NFS "server not responding" message yet. As to an earlier question about NFS options: I'm not setting any, so they are whatever the automounter uses by default. -- George
