Weeelll I have the same over-complicated kind of setup, and an Arch Linux
BTRFS system which used to boot in some decent amout of time in the past now
takes about 5 full minutes to just make it to the KDM login prompt, and
another 5 minutes before KDE is fully started. Makes me think of the good ole'
times of Windows 95 OSR2 on a 486SX with a dying 1 GB Hard disk...
Now, let me add that I had removed all snaphots, ran a full defrag, and even
rebalanced the damn thing without any positive effect...
(And yes, my HD is physically in good shape, SMART feels fully happy, and it's
less than 75% full...)
I've been using BTRFS for 2-3 years on a dozen of different systems, and if
something doesn't surprise me at all, it's « slow performance », indeed,
although I'm myself more accustomed to « incredibly fscking damn slow
performance »...
