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 Derek Holzer a écrit : > Hi Cyrille, > > cyrille henry wrote: > >> 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!!!
