Everything is working as it should, but only better. :-) Even ut2004 seems to be much smoother using staircase, some people reported 15% more fps (I haven't measured), but it runs as smooth as ut2003 did previously with Nick's scheduler (before the O(1) scheduler was updated to its current state in mm). The only thing left, which is a major pain for me, is disk i/o. Once it starts performance goes down, I think even more with staircase than with Nick's but this could be due to faster feel of staircase in general... Example: When I do a emerge rsync in gentoo a tree consisting of nearly 9000 files gets synced and a cache is built which causes a lot of random access on hd. So when I try to use thunderbird mailer at the same time, it act like a snail now due to concurrent disk access. As I understood the cfq ionice part would solve this issue. I never tried it, as I think I never had a kernel containing it (and never had such a desperate need for it :-). Reading your changelog, it is not included anymore in ck1. So should I beg Jens Axboe for a rediff or new patch or how to get this piece inside? I think it is the only thing left for the next to perfect desktop experience I ever had.
