Some scheduling differences, I suppose.

Frankly, I've done what I can with the TSO stuff at this point.

All I get from you are "it's slower" and no code, I've had to
write and fix and debug everything for you.  The performance
is close or on-par to non-TSO and more importantly TSO abides
by the congestion window and MSS values properly now.  That's
10 times more important than 2-4MB/s performance difference.

Or maybe I should revert all of the TSO work so that all SpecWEB
submissions done with 2.6.x kernels get invalidated?
