I've tried the standard settings, nice @ -19 and then up to 19, memlock at 100%, rt prio at 99. Memlock to 50%, to 65%. I haven't screwed around with rtprio much, though......
My question now, would be: what are these settings actually doing? memlock seems to speak for itself, how much available mem is set for audio purposes...right?
but I dont see the difference between rtprio and nice, I only know that they handle interrupt priority in an indirect way. perhaps i've been setting them incorrectly; for nice and rtprio, the lowest number = highest priority?
Otherwise, I just don't see why each time i changed the settings, i would get no difference. It makes sense that my cpu would be constantly running at 60% if I were to set memlock to 50 or 60%, but the xrun count was always rediculous. and yes, tried restarts each time, for the jack server, and my computer itself.
Guess I'm looking for some good guidelines to follow while tweaking this stuff, too. Like what settings might be good for an amd x2 using 2gb ram?
thanks for the help

no - the opposite is true: with a proper rt-kernel you can run critical

stuff on lower machines also. It just grabs everything your box can do
for audio...
Not really, wait until it is stable I would suggest...

If you want to try something debianish go for pure:dyne or AVLinux.
Not so much killed but died more or less without big shock and awe...

Still OpenSuse is very good for audio with the rt-kernel from jengelh
installed...
best regs
