My NAS FTP has a connection limit of 10.
On initial sync it worth having high number of transfers and low number of checkers.
(because every file found is new, and transfer takes more time)
--checkers 1 --transfers 9
But it's the opposite when I do incremental sync.
--checkers 9 --transfers 1
So I think it would be beneficial to give max number of connections, and rclone could dynamically grow number of transfers and reduce checkers.
What do you think?
