Hi,
Here are my results using Olaf's benchmark patch:
Pd 0.37.0, Pentium 4-Mobile 2GHz, winXP, with RME Multiface using ASIO drivers at 70ms of latency. Pd.exe priority set to real-time in task manager. Wish83.exe priority left at normal.
I got 745 instances of osc~ before I could barely use the GUI. No audio dropouts.
At 750 instances the computer froze, but still without any audio drop-outs.
The audio performance improvement using real-time priority for Pd.exe was quite impressive. While using Pd at normal priority I was getting occassional audio dropouts when using the GUI at about 330 instances of osc~.

G3 400MHz (internal audio, 44.1kHz):
pd 0.36 w/o -rt flag:
- 1x osc~ - dropouts when moving windows
- 140x osc~ - constant audio dropouts that get heavier when moving the mouse
pd 0.36 with -rt flag:
- 1x osc~ - dropouts when moving windows
- 340x osc~ - constant audio dropouts that get heavier when moving the mouse
SGI Octane R12k 300MHz (internal analogue IO, 44.1kHz):
pd 0.36 w/o -rt flag:
- 220x osc~ - audio dropout when moving windows
pd 0.36 with -rt flag:
- 500x osc~ - no audio drops but watchdog kills Pd when moving windows (92% CPU usage reported by top)
Pentium 4, 1.8GHz (Motu 828, 44.1kHz, asio driver):
pd 0.36 (no -rt flag, of course):
- 248x osc~ - audio dropouts when moving windows (about 70% CPU)
pd 0.36 set to realtime with task manager:
- 248x osc~ - audio dropouts when moving windows (they sound a bit different and the gui is slower...)
