hello, thanks all for your answer. yes, switching to jack improve performance, but it still not as good as in linux (i use oss).
i was able to use this computer for 2 days (it's not mine), so now i can't make more test. i did not have time to install a newer version of tcltk. does pd-extended (nightly build) use standard version of tk, or a better one? (using nightly build did not change anything)
Derek : do you know if this performance problem happend only with pd, or also with other software?
thanks Cyrille

Hi Cyrille,

now, i'd like to understand why the same computer on osX is about 2 time slower.
I've been asking myself that for years!!! I have 1.67 GHz PPC G4, and I never use OSX for live work, only Linux. It's true, the exact same patches on OSX are twice as slow on the same computer as on Linux. I've brought this up on the list many times, but the only solutions were to get into compiling against better native versions of some of the supporting software such as Tcl/Tk and X11 instead of relying on the Aqua interface, which adds most of the burden. I don't recall all the things that needed to be done...largely had to do with graphics interface (surprise surprise!)
But I didn't get too far into it. I've moved away from development/testing in the last couple years due to increasingly busy performance schedule. Easier to reboot into Linux and get on with the show! Maybe check the archives and see if it's something you want to get involved with fixing (as was suggested to me when I complained about it).
best, d.
