hi,
for rclone mount + gdrive + plex.
--- this has a set of optimized values, that uses the vfs file cache
https://github.com/animosity22/homescripts/blob/master/systemd/rclone-drive.service
--- this is another technique, does not use the vfs file cache, using the default of --vfs-cache-mode=off
https://forum.rclone.org/t/slow-scan-plex-tv-show/31492/16
--- about the api limits, notice that both rclone mount commands use the same, tested, optimized, settings.
