Can anyone tell me about experience with the QNX scheduler patch done way
back for kernel 2.0.31? I've been wanting to try it on a 2.4 series kernel
(I'm looking for best possible interactive performance under X), and I want
to know if it is worth porting to the 2.4 line.
Thanks,
Dan

You may wish to take a look at the Linux kernel preemption project at
http://kpreempt.sourceforge.net/ (official site, patch for 2.4.6)
http://tech9.net/rml/linux/ (bleeding edge, patch for 2.4.10+)

I tried the patch once or twice. On small systems or systems under heavy load it did give a more responsive feeling on interactive applications. With more modern systems (I tested it on my PowerMac 7200/75) I think the difference is not worth the effort of porting the scheduler.
