if only i'd been benchmarking writes!  i just benchmarked reads.  the
fileserver can crank out nfs at near-wirespeed (2Gbit (bonded)) esp
when working with cached files (on the raid card or in host mem), but
only seems to send smb at around 300mbits.  strangely, it sends out
multiple streams at that speed just fine, but none are faster than
that even when streaming a single one all alone.

i have to admit i was not paid to improve this, just profile it.
