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.
