He said messages/replies. The way I read that, and I might be wrong, was
that 2000 messages were being sent, ie 1000 message-reply pairs. Is that
right, or am I misreading?

also they didn't say how much processing of the messages they were doing.

and as you point out in the portion of your message that I clipped,
there's a lot more delivery overhead in a wildly multithreaded
multitasking protected memory system like Be. I'm impressed with 1
millisecond messaging... I admit I'd be impressed with 300 microsecond
delivery even more :-) Be is still in BeTa though :-). Assuming
everything gets compiled on the Metrowerks compiler, they have the
provision for some sort of profiling. I imagine things will be tuned as
they get nearer to release. I know apple often doubles the speed of
certain functions in their "system update X" releases.

BTW: Question for Be...

Are there provisions for profiling on the BE? Perhaps this would be a
good thing to put into the debug server? It'd be cool to have a
(switchable) system level support for profiling.... Also how about
optimizations? If the metrowerks compiler you're using is the same as
the Mac version, there are all sorts of global optimizations available.
What optimization settings are you using for the developer releases?
