Questions about kopia + rclone + OneDrive

I’ve followed the instructions to set up a rclone repository on OneDrive and have been actively using kopia to back up to it for quite a while. Now I was wondering if anyone has some tips on how to tune kopia and rclone to get the best out of my connection (i.e. caches, parallel access, etc.)

I have a very basic usage of kopia. I have a few cron jobs who run kopia create snapshot regularly to back up changes to specific directories and I had to space those out, so they would not interfere with each other (they seem to be running quite long even though not many files have changed)

Open for hint, tips, and links to read up on what specific parameters one could tune.
