I'm not doubting you ... but I only have four things to add:

- I can't reproduce your results ... and I'm not even coming close.
- No one has been able to explain to me what you need to do to configure
  your client, server, and hardware to get those results.
- 50 Mbyte/sec is only 40% of theoretical ... which I would call
  "not wonderful".  I can get TCP easily up much higher, and that's mostly
  out of the box.
- If the bug happens on fast SMP boxes, that makes me think things will get
  worse as systems get faster.
