Now I confirmed BTRFS performance issues:

http://arosenfeld.wordpress.com/2010/12/27/back-to-ext4-from-btrfs/

I can't keep using this thing anymore. So now the question is:

If is not possible to solve the performance issues in BTRFS, How
can I convert a btrfs partition back to ext4? it doesn't matter I have an
encrypted filesystem?

Thanks again.
