i see..... well, then i guess i have to question my memlock or nice settings again, dont I? <br><br>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...... <br>
<br>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?<br><br> 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?<br>
<br>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. <br>
<br>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?<br><br>thanks for the help<br><br><div class="gmail_quote">On Mon, Nov 16, 2009 at 4:37 PM, Hartmut Noack <span dir="ltr"><<a href="mailto:zettberlin@linuxuse.de">zettberlin@linuxuse.de</a>></span> wrote:<br>

</div>9.4 was broken 9.10 works very good for me...<br>

</div>no - the opposite is true: with a proper rt-kernel you can run critical<br>
stuff on lower machines also. It just grabs everything your box can do<br>
for audio...<br>

</div>Not really, wait until it is stable I would suggest...<br>
If you want to try something debianish go for pure:dyne or AVLinux.<br>

<br>
</div>Not so much killed but died more or less without big shock and awe...<br>
Still OpenSuse is very good for audio with the rt-kernel from jengelh<br>
installed...<br>
<br>
