Are you measuring:
OT on 9 versus BSD Sockets on X (which is often dominated by
the difference between cooperative versus pre-emptive multitasking)?
The OT shim atop BSD networking on X (which Apple claims is 5-10% slower)?

I just did some performance test on my application with OT vs. BSD Sockets.
Both versions of my application do exactly the same thing & both APIs are
encapsulated within a low-overhead class. I find that the version using
sockets is consistantly faster.
I also tested thread manager vs. MP tasks, but there was very little
difference, although I haven't optimized my code to take advantage of
preemptive tasks.
The application connects to a server which runs a script and queries certain
information from the client. Here are the average times (taken by running
each version 5 times) for deployment builds of each version, obtained by
calling TickCount before & after one server transaction:
OT, Thread Mgr: 530.6
Sockets, Thread Mgr: 351
OT, MP Tasks: 540.4
Sockets, MP Tasks: 358.4
