ACD + fuse mount: still not working with Plex

[ncw (Nick Craig-Wood)]

After some testing with 1M, 10M, 50M, 100M, and 200M max-read-ahead, I notice incremental improvement to video playback with each increase in size, though there might not be a noticeable difference between 200M vs. 100M. Improvement to video playback includes max birate that's playable, video start time, buffer time when skipping/rewinding, and time to resume video. For now I'm going to stick with using 200M. BTW I'm mounting encfs decryption on top of rclone fuse mount (not using crypt).

Thanks for testing - very useful.

I'll note that --transfers is ignored by rclone mount. --checkers is used to control the parallelism of directory listings though.

You will probably get a bit more performance turning off --debug-fuse and --verbose when you are happy.

Do you think I should change the defaults? Does anyone know what the defaults in other fuse filing systems are?

@hari9

here is the --max-read-ahead data stored? In RAM only or is anything temporarily written to disc?

It is stored in the kernel buffer cache I think. So if you do free -m it is part of the buff/cache column
