No Bernardo,
I get the same or even better latencies. Down to 5-6 ms (pd audio sttings display) with a very complex patch. Alsa is giving me more problems like digital A/D/A sync errors. As far as I know alsa is using oss anyway. Not sure if I'm wrong here.
Anyway, I just figured out what the problem was. I had a "-blocksize 64" flag set when starting the patch. Changing this blocksize to a higher value like 512 did the trick. Now higher delay settings have an effect.
Seems a bit strange to me as the actual blocksize doesn't seem to change but the maximum buffer size is increasing.
It also like it's giving me a slightly lower cpu consumption (10-20%). I'll have to try different values in order to see what seems to be the best setting.

Ingo, I think OSS can offer you just very high latency. You can't get realtime with it. Did you test this "8ms" latency, is that actually waht happens?
I get latencies as low as 5~10 ms with alsa and jack.
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.
