There are some Linux modified scheduler on Internet.

The best one for general purpouse application is QNX-like scheduler patch from Adam McKnee ( It is a patch for kernel 2.0.32.

I am testing the performance of this scheduler for a University exam and the preliminary results says it is better than standard one .

It would grant good interactive performance under heavy CPU load.

You can find the patch at or by contacting the autor.

Hope this helps
