Interesting.  On my laptop I'm seeing 113MB/s with TSO on and
119MB/s without.  However, netperf shows TSO on is slightly
better than TSO off (4716Mb/s vs. 4680Mb/s).

A packet dump on tbench indicates it's sending lots of small
packets so TSO wouldn't be contributing anything positive at
all.  Hmm, it seems that even netperf isn't producing anything
larger than MTU so something seems amiss with the TCP stack.

BTW what were the actual numbers on your machine with tbench?
And what about netperf?

Cheers,
