While dd'ing to an nfs filesystem, half of the bandwidth is unaccounted for. What dd reports amounts to almost exactly half of what zpool iostat or iostat show; even after accounting for the overhead of the two mirrored vdevs. Would anyone care to guess where it may be going?
(This is measured over 10 second intervals. For 1 second intervals, the bandwidth to the disks jumps around from <40MB/s to >240MB/s) With a local dd, everything adds up. This is with a b41 server, and a MacOS 10.4 nfs client. I have verified that the bandwidth at the network interface is approximately that reported by dd, so the issue would appear to be within the server. Any suggestions would be welcome.
