It was working pretty well when we were using 2.6.27.x, but after upgrade, I also changed FS from XFS to ext4, (so I can't easily test with 2.6.27 now) and since then NFS is almost unusable on this machine. But 2.6.27 is pretty old, so there's been a lot of changes. But greg released 2.6.32.9-rc1 which contains bunch of NFS-related fixes, so I'll give it a try and report. nik On Sat, Feb 20, 2010 at 06:51:05PM -0500, J.
