There cannot possibly any compliance issues resulting from turning
off an optimization in the face of packet loss.

And running the benchmark over a local gigabit subnet doesn't deviate
from what Internet connected systems can expect to achieve how-so?
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
Furthermore, all the tuning people do in each run is to optimize
specifically for a local high-speed interconnect subnet, no limits
on TCP or filesystem memory use, and large cache sizes. Nobody
configures their machines this way, unless they want remote users
to be able to consume %90 or so of their system memory with TCP
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
