Hi,

I have 4 machines, all converted to BTRFS about 6 months ago, now all
running Ubuntu Quantal with kernel 3.5.0-17

The matter is that all these machines are now getting slower and slower
everyday, every disk access causing the disk to be 100% busy for long
periods, to the point that I'm now seriously considering migrating
everything back to ext4...

>From the start BTRFS was "not very fast", still satisfactory, but now it
becomes truly unusable.

On one machine, I know have a typical complete boot time to a usable GUI
that is over 4 minutes, with the HD still very busy for a couple more
minutes afterwards, where it used to be around 35-40 seconds in ext4 !

Is there anything I could do to speed things back (without losing all my
snapshots or doubling the size of data on disk)...?

I already had made the move back from BTRFS to ext4 about 18 months ago,
I found it had improved so was back to BTRFS, and I wouldn't have to
revert back again :-/

Any advice or help greatly appreciated.

TIA.
