Yes, I am using this as my mount options: mount -o rsize=32768,wsize=32768,nfsvers=3,noatime nas:/Access.Share/system_images /mnt/images I have also tried with a few different wsize and rsize like for example 8192 and I tried mounting with no options at all. I am using UDP and cannot try TCP because my NAS server does not currently support it. This is the output of nfsstat -c on the client after about 400Mb transfered at which point I canceled the transfer because otherwise it would take forever. Interestingly the transfer starts at a screeming speed in comparison to a 2.4 kernel NFS client but then it all stops and kind of bumps along. I am running on 100Mpbs ethernet, non switched but for the moment there is no other traffic on the lan. My test basically consists of running partimage to back up my disk partitions to the nas.
