Last time we talked to the kernel folks about an rt kernel, they weren't impressed with the "need" for Fedora, but that was before the Spin was officially out.
Now might be a good time to raise this issue again? I dug through my archives and found this thread. Now that we have an actual spin that's out, we can actually redo some of the testing to have more realistic tests. (multitrack with effects)

I feel like right now, it's one of the few benefits that the ubuntu studio folks have (or at least claim to have) over us. The other is some semi-proprietary software that on... you know what, never mind it's getting off topic.
Anyways, does the list think this is worth pursuing?

Ok, I redid all the tests, while the system was only running my DE and the test, and then again when I put it under duress by running a script that looped "du -h /" and "ls -Ral /usr/" over and over. I ran the script twice to get my proc up a bit to emulate running some intese delays and reverbs or other effects.
Ironically the kernels typically did better when the scripts were running. Personally I think there's a clear advantage with CCRMA's kernel or even just a preempt kernel in the max lat areas. Those max numbers jumped up close to where they were near the beggining of the test if anyone was wondering.
Here's the file with both sets of tests and the uname -a info as requested by Fernando.

I'll be sure to include that on the next batch. I used the kernel you after installing the CCRMA repo when you use yum install kernel-rt, which happens to be 3.0.17-1.rt33.1.fc16.ccrma.x86_64.rt. I'll go back and include the other info to the old results when I do the load testing tonight or tomorrow.

Bah, I forgot to save before I uploaded, here's the text file with the
CCRMA results.
Hi Brain,
Argh, Brian, of course... sorry...
and thanks for testing and sharing the results.
Which CCRMA rt kernel were you testing? It'd be nice if you did an uname
-a before each test...
