With the new patch I'm getting 78.0%.

Thanks for testing.

I actually expected the new code to do better.
Splitting could be a little bit expensive, but
that only occurs at the beginning of the connection
as we ramp up the congestion and send window.
Afterwards, we should be able to release full unsplit
TSO frames onto the wire.

With different (larger than default) buffer sizes, I'm getting 63.4%. Not surprising I guess.
