[very quietly] I've had autodefrag out of my mount options for a
long while now. Is that still the recommended position?

I think it really depends on what you're doing.  In my case, I
usually have it on, and the only issue I've ever seen is that Chrome
sometimes loads pages from local cache slower than it should be.  I
also don't use ridiculous numbers of snapshots either (I use them
only to get a stable view of the filesystem when generating a
backup), so I don't have much experience with how they interact with
autodefrag.

I'd recommend to set chrome caching to simple http cache in
chrome://flags as this is more suitable for btrfs (as for most Unix
file systems which deal with many small files better than with random
updates in a big fat files).

I experienced much improved performance and responsiveness with it. May
be worth a try for you. I'd be interested in your results.
