I did some benchmarks against rclone today. https://greaber.github.io/syq-bench/rclone.html Syq was sometimes much faster and never more than a few percent slower. I didn't do any tuning of syq since it is meant to perform well without any special options, but I did tune a couple of rclone options. It's possible that more extensive rclone tuning would yield better results though. Please let me know if there is anything I need to try!
