I don’t know if this applies to you, but don’t use the compression flag (-z) for files that already is compressed (like video). The transfer will get CPU bound quickly if you have a fast internet connection.
I went from 13 Mbytes/s to 200 by removing the -z flag, and the compression ratio was non-existant anyway.

My understanding of rsync was that it was pretty painfully slow.

I use rsync for this purpose and the only notable bottleneck is my download speed, fwiw.

How did you “understand” that it would be slow? Did you look at the code?

The only time rsync is really slow is when your dealing with millions of small files since it only transfers a single file at a time.
rclone is better in that respect since it transfers multiple files in parallel. I don’t think the speed of a single transfer is going to differ much.

That must have been it, appreciate the clarification.
