The CFS was merged ages ago and there is a very wide consensus that it gives the same kind of interactivity boost as CK:s rotating staircase. On top of that the control groups for CPU slicing will be available in F10. There is no consensus of how to make use for it in the desktop scenarios though, so won't add much as for now. Control groups look like they will be able to e.g. prioritize things like the memory hierarchy and network traffic for the desktop use case (as well as other use cases) in the long (well, some year or two) run, but it is being intensely developed right now. Swap prefetch was the most interesting patch from the CK tree IMHO: http://lwn.net/Articles/242765/ Sadly I don't know what has happend in this regard :-/ Anyone else? While we're at interactivity, there is this thing called "ionice" that interacts with the CFQ I/O scheduler from userspace. It is probably a good idea to "ionice -c1" (realtime) things like your Gstreamer or mplayer, and "ionice -c3" (idle) your transmission bittorrent client, updatedb or backup tasks. I do this manually from time to time, but cannot really claim I notice any big differences. Such heuristic ionice:ing is nowhere to be seen, does anyone know if it is being looked into anywhere at all? All in all, there are popping up some real nice interactivity features in the kernel, but AFAIK noone is really working on using them in the desktop usecase. Just my Euro 0.01...
