Hey Ingo,

I recently happened to come across this thesis[1] which
presents some very concrete results with stats regarding
the performance of Linux CFS with an implementation of Redline.

It would really be great if you could take some time out of your
busy schedule and quickly look up the figures to see the performance
comparison and if we could adapt some ideas. I am willing to give it
a try if you think its worth it.

Thanks,

Looks to propose a rather simple semi-static edf based cpu scheduler.

If you're interested in that, there is a group actively working on a
deadline scheduler for linux: http://lkml.org/lkml/2009/10/16/161
