FreeBSD 7.0-RELEASE available

Is CFS that bad? Anecdotally, I am seeing quite poor multitasking performance on Ubuntu Hardy over here (bug: https://bugs.launchpad.net/ubuntu/+bug/190754 ). I've heard some people blame CFS for it, but I really have no idea if that's the case. Perhaps someone here knows more?

I've noticed a lot of latency issues on my laptop running Gentoo, which is generally compiling endlessly (i do a lot of gcc snapshot testing against our tree) which began around the time the kernel switched to CFS, though I can't say it's anything but coincidence and wouldn't have the first clue how to go about finding out. Again, anecdotal evidence, which is usually worse than no evidence at all. ;)

My anecdotal evidence is that CFS gave my Gentoo-compiling laptop much, much better
interactive feel.

The thing that hurts interactivity for me is disk writes, the IO queue fills and then its
goodbye disk scheduling, hello, pause, page-in, pause, screen update, pause, lag, lag, lag.
