The Linux client is however strongly influenced by device mtu. I am current= ly operating both server and client at an mtu of 9000. If I lower the mtu to 1= 500, the Linux client performs *very similar* to the FreeBSD client (at any mtu), delivering 200-250 MiB/s. I think, it is strange that the FreeBSD NFS client does not benefit from a = mtu higher than 1500. Could this be a hint at what's going wrong? --=20 You are receiving this mail because: You are the assignee for the bug.=
