I'm running FreeNAS 8.0/amd64, with an 8.2-p1 kernel.  When using FTP
or SCP, performance maxes out around 30MB/s. This is on a gigabit
network, no errors showing. 

It looks a lot like kern/152828, but it seems that nobody's looking at

As per suggestions from the archives, I've tried disabling TSO. No

Anyone else experiencing this, or have any suggestions? At the moment,
the boss is complaining that his Windows Home Server is doing better
than this machine, and that's a technological direction I really don't
want to go in.
