d'oh... no such tools in Pd. (Was there suc ha thing in Max/FTS? I don't remember it :)
maybe its to long ago, but I thought in max/fts you could print out a "time of operation of each object in the dsp-stack over an amount of ticks on the console, but maybe I am wrong and only we did it an IEM to track down DSP-efficiency.

Hello,
I've been getting various real-time problems too, but I'm not sure whether to blame the new Pd version, or the 64-bit kernel, or the new machines I'm running it on.
Just to make things one bit more compicated, I've updated the included version of portaudio and added optional callback scheduling too -- I'll probably upload changes to CVS after another day or so of testing.
just found out that afeter 2hours and more, netconnections between GUI-Instance and PD-DSP become notible long (> 300ms), maybe the networking ?
But since one rule is, never guess, measure why, I have a quick question. Is there a profiling tool on oject or message base ? I can remember there was one in Max/FTS, so I can find out the bad objects... ?

I think most of the 64-bit bugs only got cleaned up for 0.41 (and the test version in CVS is pretty stable at the moment)
ok, I give it a try tomorrow and post back here. Thanks for the info,
just run 0.41 on 64studio 64 bit and a complex patch (CUBEmixer) just run fine. But the disk access makes a DAC-slip on the 2.6.22 realtime kernel, much worse than on non-realtimekernel. Is there anything to adjust on the kernel site to get better disk access scheduling ?
