That's the preempt chaps =)
Well, I've been using the kernel pre-empt patch for 2.4 for a while. I'm imagining it's actually the much better scheduling and IO systems that do it most. :)
Pre-empt, lock breaking and oodles of other little goodies were fun. Since using 2.6 and reverting back to 2.4. I've noticed huge amount of differences between the twos.
Anyone using pre-empt or other patches on servers?

I have spoken to some people about this. I have a good friend Kevin who is interested in music, and he has told me about some of his experiments with alsa, low latencies and preemptive kernel patches made, it was also interesting how that they worked together.
My mane interest was to be like windows and be able to play an mp3 some thing I never had done before, under linux this used to just stutter making the idea of playing them too unpleasant to bother with.
me how much difference to audio this sort of patch made on a poi 266 and how my p1MMX 200 would benefit too. Kevin did the full test and is now using both patches as their effect only complements one and other. The low latency and the preemptive after I did it for my own interests.
When I spoke to System administrators (whose systems do calculation and IO) they where interested until they realized that the performance difference was mainly in interrupts and actually reduced server throughput marginally.
