SubjectCsound Performance on Multiprocessor Intel Systems?
Hi all:

Does anyone know about the performance of the various Csound types on
multiprocessor Intel systems?  I am frustrated with making a change that
requires 30 seconds of typing, and waiting 20+ minutes to hear the
results.  Yes, I know that this is a modern miracle, that back in the
old days you had to walk 10 miles in the snow to put the punchcards into
the IBM 360, then a week later drive 40 miles to the AD convertors, etc
etc. - but if I could get an improvement over what I currently have, it
would drastically improve my productivity, as I could shape compositions
much quicker.  

Would standard Csound's performance be improved with a multiprocessor
system, or would it have to be rewritten?  Can any of the other Csound
variants like DirectCsound or the Linux Developers Group Csound take
advantage of a dual processor system? I don't have any experience with a
dual processor system, so I don't know if there is a general increase in
performance, or if the program and/or operating system have to be
(re)written to utilize the dual processors.

I am not necessarily talking about real-time stuff, which seems best
left to a Macintosh (or perhaps the BeOS at some point in the future). 
I would like to simply cut down the compiling time for orc/sco
combinations that use computationally intensive opcodes (sndwarp, pvoc).
Does anyone on the list have experience with a dual processor system, in
either Windows or Linux?

Thanks,
