Yes, this is familiar. I too have used it for over a year. I am only
using it for /home since the file fragmentation problem was unbearable
in /var running yum. The performance problems I experience now are
probably related to this:
https://btrfs.wiki.kernel.org/index.php/Gotchas (first issue)
The last time I tried mounting with autodefrag, it was not much
improved and I worried that my kernel was not new enough to run that
mount option. Now that I just upgraded to F18, I will try again.
The bottom line from my personal experience is if the autodefrag
option works well in /home, I would say I'm ready to see btrfs as the
default. Otherwise, it would probably be a problem on workstations
and certain server environments.
Aside from performance, it has been flawless for me over the last year
or so.

This duplicates my experience. I don't have anything intelligent to
say about it either. :-)
