I think you might have got this backwards Luke. The results I've seen
show Linux/Samba beating NT for small numbers of clients and losing
for larger numbers (at least with a 2.2 kernel). See for example

I really am _very_ skeptical about threading/non-threading having any
impact on netbench results. I'm sure it would be possible to carefully
construct a benchmark where threading matters, but it would have to be
pretty strange.

Does anybody have any non-anecdotal evidence that the lack of
intra-smbd threading is hurting our performance?
