. Merged up John's latest 2.5 oprofile, so folks will have to wean
themselves off the crufty old one.
You'll have to grab the userspace tools from
http://oprofile.sourceforge.net/oprofile-2.5.html
Use:
mkdir /dev/oprofile # John forgot this
./configure --with-kernel-support
make install
Or just do what I didn't do and read the web page.
Quite a few things seem to have changed with oprofile. A typical
profiling cycle would now be:
rm -rf /var/lib/oprofile
op_start --ctr0-count=50000 --ctr0-event=CPU_CLK_UNHALTED \
--vmlinux=/path/to/vmlinux
<run test>
op_stop
sleep 3
oprofpp -l -i /boot/vmlinux
kill $(cat /var/lib/oprofile/lock)
You must kill the daemon by hand before you can run op_start
again.
. I've dropped the 512-byte O_DIRECT alignment patch for now. It's
over in the experimental directory. I'd like to get a decent round
of testing with the bio_add_page fix so we can get that into Linus
and get direct-io generally stabilised again before moving on.
. We've had some encouraging performance test results on the
shared pagetable code, but also a couple of crashes. The people
who are monitoring performance may want to try that out. It is
selectable in config.
. Turns out that the idea of unmapped mapped pagecache a little earlier
than swapping out anon memory was a poor one. Changed the VM so that
we treat these types of pages the same.
It would be really appreciated if people who are interested in "the
desktop experience" could give this patchset a try. It's working
well for me; but that's not a large sample...

Sorry. Twas a strategic typo. "unmapping mapped pagecache".
What I was doing was to reclaim file-backed mmapped data a little
more eagerly than to start swapping anonymous memory. Under the
theory that program text can be reestablished with one IO, but swapout
needs two.
Disabling that cool idea made things heaps better, so....
I assume what was happening was that we'd reach the "reclaim mapped
pagecache" level, reclaim a ton of memory and then never start
swapping.
Actually, the thing which throws the spanner in the works, again and
again and again and again is having lots of dirty pagecache around.
The more stuff I put in over there, and the more the kernel clamps
down on the heavy writers, makes them write back their own data (actually
their own spindle....) the better things get.
Here's the diff. It is really just 2.4 in disguise.
