Hi everyone,
I'm just writing to say how impressed I am with the new CFS scheduler. I've been following it's development from the first patch, right up to now (running on the latest vanilla kernel I could!) and I can honestly say I've never had such a responsive experience.
I'm currently writing a major patch to the ext2 file-system driver, as part of a University project - it involves a lot of kernel rebuilds as I'm testing the patch in UML. I've had a couple of kernel compiles happening simultaneously (on my moderate single CPU PC), and tried out a few make -j12's, and I'm amazed at the difference the new scheduler makes.
I've got quite a few instances of Firefox (whoops, Iceweasel) open, I'm listening to music and theres a few other apps running (like KNode the newsreader) and the interactivity response has been excellent.
In conclusion, well done to the scheduler people and I look forward to seeing this go to mainline.
(If there's anything I can do to help, I'd love to throw a few patches at the mailing list ;)
