As such, the hit is most likely a network fabric issue or a ZFS issue. The only thing I can suggest to try is: rsize=3D131072,wsize=3D131072 It should perform about as well as 1Mbyte, but??? If it does help a lot, there is something in the network fabric (most likely the NIC/driver) that cannot handle the burst of TCP segments well. Did you happen to have "sync=3Ddisabled" set on your 13.2 ZFS. Setting this runs the risk of data loss when the NFS server crashes/reboots, but will help w.r.t. write performance. --=20 You are receiving this mail because: You are the assignee for the bug.=
