One thing that stands out on the Mac OS X front is the fact that Pd
is using the double precision math functions even though Pd uses
single precision floats. You can see it here:

Here's a previous discussion on this:
http://lists.puredata.info/pipermail/pd-dev/2006-01/006042.html
I don't think this would make a massive difference overall, but I'll
bet it would make a significant difference for any patch using sin,
cos, atan, atan2, sqrt, log, exp, fabs, or pow. Anyone feel like
writing a patch to make ./configure set things up properly?

I second that. If your main motivating factor is performance,
Linux is the way to go. I too run a dual boot Linux/OSX system on
my 2nd notebook, and have found Pd patches running in linux to run
with much less cpu load than OSX. If you choose to use JACK
instead of Portaudio on OSX, you can reduce their cpu load
significantly (fyi, JACK isn't yet compatible with 10.5). The Mac/ Linux system is probably the best of both worlds + you can satisfy
your OS X package needs with Darwinports (which rocks).As for windows, haven't used it for audio since 1999 and don't
intend on going back.Do you have any other main considerations besides price and
performance when looking for a new machine?~Brandon

Hello all,
I was wondering if anyone has done any sort of "Platform"
comparisons? I am in the market for a new machine, and was just wondering if
there were any performance comparions for the various platforms for which PD is available.More than enough stuff in the archives about this. My take:
I don't know anything about Windows, haven't touched it since
2002. I do find that quite a bit of PD is either optimized for or developed with Linux on Intel architecture in mind. You have the widest choice of objects available and often running better than on any other
platform.Additionally, I run Gentoo and OSX both on a PPC Powerbook and discovered long ago that patches running on the same machine and
same PD version are more than twice as fast on Linux as on OSX. There are probably many reasons for this, the most recently-discussed one
was the interface with Core Audio.If you're up to it, a Linux partition on an Intel machine (Mac or PC) would be the highest performance way to go. That leaves a lot up
to you still.best, d.
