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_.
Cheers,
FJP
