(4 cores already is today, 8 threads is that any day now) Despite that I'm personally more interested in what I have available here *now*. And that's various UP Pentium systems, one dual core Pentium D and Core Duo. I've been running BFS on my laptop today while doing CPU intensive jobs (not disk intensive), and I must say that BFS does seem very responsive. OTOH, I've also noticed some surprising things, such as processors staying on lower frequencies while doing CPU-intensive work. I feels like I have less of the mouse cursor and typing freezes I'm used to with CFS, even when I'm *not* doing anything special. I've been blaming those on still running with ordered mode ext3, but now I'm starting to wonder. I'll try to do more structured testing, comparisons and measurements later. At the very least it's nice to have something to compare _with_.
