Thanks Duncan for all this excellent discussion.
However I'm still rather puzzled with a filesystem for which advice is if you
want tolerable performance, you have to turn off

Yeah, I have experienced this, too. I can't say what your experience
was, but mine

I no longer see the slow degradation over time because I made the

OK, we now have a second link to akonadi (and browsers) and slowness,

hi all,
Btrfs falls into hang when I ran iozone test with the following configuration:
./iozone -s 8g -i 0 -i 2 -i 1 -t 4 -r 4k -+w 50 -+y 20 -+C 60 -F
/mnt/btrfs/test1 /mnt/btrfs/test2 /mnt/btrfs/test3 /mnt/btrfs/test
The bug can be very easily triggered when running this test in my PC.

Hi Filipe,
Can you please explain more what is the scenario you are worried about.
Let's say we have two FS trees (subvolumes) subv1 and subv2, subv2
being a RO snapshot of subv1. And they have a shared subtree at
logical==X. Now we change subv1, so its subtree is COW'ed and some
other logical
