Ingo, I think OSS can offer you just very high latency. You can't get realtime with it.
where did you get that piece of information?
the lowest latency i was ever able to get with Pd at 44.1kHz was with RME Hammerfall and OSS(!) drivers: 4.8ms measured(!) between soundcard input and soundcard output, and that at a load of 80% or so.
(i don't fully trust in the numbers that you can fill into the various forms, regardless of Pd, jack, or whatever; the only way to get yuor latency is to measure it).
the main problem with OSS is, that it is simply not available anymore on recent debian/ubuntu/... distros.
Besides, if you configure your system right with ALSA and JACK, you don't need to run PD as root. Don't run programs as root, this is not safe.
i couldn't have said that better.
