Should we limit concurrent file transfer to 1 when using rclone?

In the Backup With Duplicati doc, there is a recommendation about limiting asynchronous-concurrent-upload-limit to 1.

By default, Duplicati will transfer 4 files in parallel in order to speed up the transfer. The Storj protocol splits every file upload into many small pieces and uploads them in parallel. Even with only 1 concurrent upload it should max out most consumer connections.

Should we do the same with rclone by using --transfers=1?

Hello @weeix ,
Welcome to the forum!

Only if your upstream bandwidth is too low (less than 25Mbit).
