Hi there,
# uname -r
3.13.6-1-ARCH
# btrfs --version
Btrfs v3.12
After having read the recent discussion about rebalance, I ran it for a test
on my laptop with a 1TB HD, which current situation (after rebalance) is :
# btrfs fi sh
Label: TETHYS uuid: 9a1ca6f4-1c1b-4a62-a84b-b388066084dc
Total devices 1 FS bytes used 575.56GiB

Btrfs v3.12
# btrfs fi df /

/dev/dm-3 845G 578G 266G 69% /
The rebalance for the biggest BTRFS took about 19 hours.
I was expecting either a speed improvement after rebalance, or no noticeable
effect, but I am extremely disappointed to see that now (and after having
rebooted), my system has become slow like hell, takes at least 10x longer to
boot and operate, to the point it has become hardly usable :-(
I would have thought a rebalance would have improved the filesystem
organization, looks like it's the absolute contrary :-(
