Hey Chuckk
My knowledge is patchy, and it's likely some folks can give you better advice here, but here's what I have to offer, as a DeMuDi user for several years...
All your latency settings are done in Jack, and you should have no problem getting the same or better performance out of Agnula than Windows. Make sure "realtime" is on in Jack setup (this makes a huge difference), and make sure you have decent buffer sizes. I think my P4 2.4 can get less than 6 ms latency with no troubles.
Make sure you start pd with the -rt and -jack flags.
I sometimes get clicks when editing, but that's all. Also, I think DeMuDi stable has an oldish version of pd. You might consider compiling 0.39. DeMuDi unstable is more up to date.
And to make matters worse, Ubuntu has a really good Pd package, and while Agnula's easy to install, Ubuntu's _really_ easy to install. The only thing is you don't get the realtime kernel, but Frank will tell you you don't really need it with more recent kernel versions, and I agree, at least in the case of my PC. (thanks Frank)
Hope this helps, and I hope I'm not saying a bunch of stuff you already know.
cheers dafydd

I just installed AGNULA DeMudi Linux on my 2nd hard drive, so that I now have WinXP on the first HD, OSX on a G3, and Linux on the slave drive in the Windows box, and PD running on all three. I'm hoping to gain experience in all three OSs.
I'm finding DeMudi really buggy though. I guess it's just the little things I've learned to work out in Windows but not here. At times, using Jack, the Jack icon goes red and I get a bunch of DIO errors in Pd, and I find that I can no longer use any of the menu options in Pd. Obviously I'd like to avoid this, but I tried it again and can't reproduce it. When it happened, I closed and restarted Pd (thankfully I wasn't actually working on anything) and in the Jack connections, the old instance of Pd remained in the MIDI tab.
Also, my latency is higher than in Windows. Pd starts up set to 50, and by the time I have Jack, Pd, and Ardour open, I'm getting errors, even with no patches open. Is this common? Are there settings I don't know about, or is Linux inferior to Windows in this regard?
There are other times programs just don't start when selected in Linux, and right now I have the Jack control open but the icon for it has disappeared. I've installed this same Linux distro 3 times in the last day due to various problems. It's the latest "stable" DeMudi, with kernel 2.6.12-3.
