With the ATI bug I was hitting earlier fixed, only my btrfs partition
continues to show high cpu usage for some operations.
Rsync, git pull, git checkout and svn up are typicall operations which
trigger the high cpu usage.
As an example, this perf report is from using git checkout to change to
a new branch; the change needed to checkout 208 files out of about 1600
total files. du(1) reports that the checkout is about 14 megs; the
alternates for that tree have about 60 megs of git packs.
As you can see btrfs_find_space_cluster(), find_next_bit() and
find_next_zero_bit() use most of the sys cpu. That patterns seems to
hold whenever I run perf top during such operations.
Box is x86_32, pentium3m.

Ok well thats a bummer. Would you mind trying this completely untested and
uncompiled patch :)? I think we should probably not be trying to use a bitmap
unless theres quite a bit more free space in it than what we need, since they
can span 128mb, and instead of cycling through the extent entries we should
probably just search for the next bitmap to make it simpler. Let me know if
this helps or not. Like I said I've not tested it or anything, so it could make
things blow up, but I don't think it will. Thanks,
Josef

It is compiling now. I might not be able to reboot until tonight. And
I'll want to do another incremental backup of the fs. (I'm using it in
production in part because it only has mirrors, checkouts and the like
and because I have that backup.)
I'll reply again once I have results.

The patch did improve the CPU usage, at the expense of IO latency and
block/cache usage.
Just after booting, and with crond down so that nothing competed, I
tried a git pull in a not-too-stale clone of cairo; it took about 6=C2=BD
minutes of disk i/o before git-fetch actually grabbed anything across
the net; that filled the fs cache (ie, about =E2=85=93Gig usage).
Once that initial pain was over, everything I tried was much faster tha=
n
w/o the patch, until I restarted crond and let mail flow in. With the
added paging pressure from uucico, uux, and all of postfix=E2=80=99s an=
d pgsql=E2=80=99s
processes the delays when operating on the btrfs fs were significant.
I do think, however, that they were still faster than w/o the patch.
But that is subjective.
The only dmesg differences were a single btrfs-transaction blocked for
more than 120s notice:

And this one line notice:
[ 115.801909] device label bay0 devid 1 transid 5397 /dev/sdb2
which may have been at the point where I mounted /dev/sdb2 or may have
been during that first git-pull I mentioned above. The 360s mark was
certainly during that git-pull.
There are also these notices in dmesg, but I see one of them in /var/lo=
g
from an earlier boot, w/o the patch, so they are only more frequent on
this boot, and therefore unlikely to be related.

All in all, the patch seems to be a progression.
The perf report of that first pull is below; top(1) showed i/o wait
