I have tried both the 2.0.6 and 2.0.7rc3 releases. I also tried the git repo version but there is some sort of an issue with lockups with it right now so I'm just using the release version. I am not modifying the wsize version on this particular mount as unfortunately the way the server works does not allow to set options. I don't expect it to run as fast as possible like that, but still it should get more than Kilobytes/sec... megs or more are what I expect to see. The servers are currently at the default slot entry numbers. I tried increasing them to 128, which is what the NFS optimization guides out there recommend and it only very slightly helps with the write speed. I do have write-behind enabled. I just tried to disable it and see if that made any difference. It went from ~600KB/sec write speed to ~800KB/sec.
