Same values for me with same hardware running 10.6.2 and Pd-extended 0.41.4. After using Pd on Linux for some years, I was expecting to experience the dreaded OSX "slow pd and midi syndrome". So far I haven't had any problems of the sort and my patches run just as they do in Linux with -rt. Of course I'm not using GEM and I'm not running 20 other applications at once as most mac users seem to do ... > On Sat, Mar 6, 2010 at 10:25 PM, B.
