I have a directory with 10GB (1M files) in it. rclone sync is taking multiple days to upload it to OneDrive.
I have a dedicated 11Mbps uplink. With my uplink speed this should take 2 hours. As proof, I was able to sync directories with 100GB (but with fewer files) in less time than it is taking to sync this little 10GB directory. So I conclude that the 1M files is adding days of time. I don’t even see how this is possible. My ping time is 30ms. Even if software is dumb enough to handshake every file individually, and only do one handshake at a time, and each handshake is 3 roundtrips, it shouldn’t be this slow. What could be going on and how might I fix it?
