Set this up on my laptop yesterday with some awesome results. I'm using 2.6.17-ck1 which has v2.1. Heres some bootcharts, before, after, and a prime run. http://archlinux.org/~james/normal.png http://archlinux.org/~james/fs-fcache.png http://archlinux.org/~james/fs-fcache-prime.png Repeated boots show about the same 6 second improvement, 32 down to 26 seconds. Looking at the slowdowns in the fs-fcache run, most are due to cpu load, waiting on network or, modprobe, and not disk access. X now starts nearly instantaneously. As an experiment, I primed my cache right through to logging into my desktop environment. It was so effective, that now when I login, the GNOME splash screen only flickers onto the screen briefly, and the panels appear almost instantly. This is a big improvment over without fcache, where you'd see each component of GNOME being loaded on the splash screen, nautilus, metacity, and the panels would take quite a bit of time to render and load all their applets. Impressive work, I hope to see it broadened to other filesystems, improved and merged to vanilla soon because it has clear improvements.
