Besides Scalability there are other attributes where
btrfs exceeds other filesystems.

Regarding the scalability part, lets not compare something from 3
years ago, lets compare the 13.1 kernel, kernel 3.11.0. Ext4 has had
pretty nice improvements in 3.11 regarding scalability, see
http://lkml.indiana.edu/hypermail/linux/kernel/1307.0/00286.html for
details.

You might or not like this benchmark, but the headline is pretty
clear: "EXT4 wins".

And, they didn't check, but at least for database workloads ext3 beats ext4.

So, if btrfs is slower than ext4 by that much, then for databases it's
a no-no (ext4 is already a no-no, so perhaps I should say
no-no-no-no-no)
