Thank you for the reply.
I must confess I have sort of "inherited" these settings/variables when I found out rclone could be used on my coreelec-box, and they have worked, so I have not done any more research to improve it, but now that I have had some problems with my OSMC-box I would like to make it as good as possible.
--fast-list will be removed
dir-cache-time= what is the better choice here ?
--allow-non-empty will be removed if possible.
buffer-size and chunk-limit were one of my "inherited" settings. Should they just be removed ?
Thank you, I will try to move the rclone mount line!
