As others have noted, GEM performance is generally pretty good on ther
current Mac line, espc compaired to PDP which is heavily optimized for
Intel processors (perhaps a benefit on the MacTel?). Although I have
seen situations using a firewire camera where a GEM patch suddenly eats
2-300% of the CPU it used every other time you ran it, which I suspect
has something to do with the drivers used.
But for audio, PD on OSX performs quite poorly in my opinion. Patches
which run quite comfortably on the same machine under Linux have
staggering dropouts and the GUI responds quite slowly or not at all when
doing any serious audio processing on OSX. I have tried all available
installers as well as compiling myself (outside of the build system) to
remedy the problem but haven't found any solution that really works.
Perhaps using the latest Tcl/Tk packages would help, but I haven't been
able to trick PD into compiling against those yet ;-)
All in all, I won't be using PD on OSX for any live audio work any time
soon when performance is far superior under Linux. Perhaps others have
different experiences, however.
