It's likely been broken for a long time, but I don't use t= he NFS client functionality much (I haven't needed to read/write something ove= r it in a few years, previously it worked perfectly). I noticed it because that= was about to change, and the NFS client was going to become more important. I can't get more than about 180KiB/s over NFS at the moment. I haven't tried the intel-em-kmod drivers yet, but I probably will tomorrow (it's late here= at the moment). The remote NFS server is fine and performs as it should, it can kick out ar= ound 1Gbit/s to other (non-FreeBSD) machines no problem. It should also be noted that in at least my case, the NFS server on this FreeBSD machine continues to work just fine, and I can read/write to it at = the speed of the network. The poor performance is strictly limited to just the client. I don't really have anything else to contribute, and added this information just to check that someone knows that this is still a problem.
