I ran into a performance issue with rclone v1.50.2 & the new linux kernel 5.4.0
- rclone mount (google drive, crypt)
- measure transfer speed of a plain file copy operation (either cp/time, dd, pv)
- linux kernel 5.3.8 or lower: speed well beyond 300mbit/s up to 900mbit/s (gigabit line)
- linux kernel 5.4.0: speed max 20mbit/s
same mount command/params, just rebooted with another kernel several times, same result. using "rclone copy" instead of the mount always works as expected with up to 900mbit/s
Can anyone else confirm this behaviour?
