The other relates to the business of disabling TSO on a connection upon packet loss.

There cannot possibly any compliance issues resulting from turning
off an optimization in the face of packet loss.
I was a bit vague - compliance with the benchmark run and report rules, not with 
RFC's.

Internet connected systems experience non-trivial packet loss rates and so if TSO 
disabled upon packet loss it means a given benchmark result using TSO deviates 
even more from reality than one without TSO.

And running the benchmark over a local gigabit subnet doesn't deviate
from what Internet connected systems can expect to achieve how-so?
Benchmarking, not logic...
Oh you mean I really can get 60,000 web or database connections a second
when the users are over modems half-way across the planet?  Give me a
break...
If there are enough users :)
Anyways, see my other posting, we'll be able to keep TSO enabled in
the face of packet loss, but that is an optimization not a correctness
fix.
Cool.
