To test rclone I copy a folder with 165 files (1-3 MB each file, 330 MB in total) to my OneDrive Business account.
I'm attempting to get maximum upload speed on my 100 Mbit/s internet channel.
I've got the next results changing "--transfers" parameter:
I wonder why did upload speed almost stop growing after "4"?
Another software I tested (AirExplorer, Syncovery) do about 8 MBytes/s with 8-10 threads on my channel and almost saturate it with about 15-20 threads.
What is your rclone version (output from rclone version)
rclone v1.55.1
Which OS you are using and how many bits (eg Windows 7, 64 bit)
Windows 10, 64 bit
Which cloud storage system are you using? (eg Google Drive)
OneDrive Business
The command you were trying to run (eg rclone copy /tmp remote:tmp)
I wonder why another software I tested (AirExplorer, Syncovery) is able to saturate my channel (100 Mbit/s = 12.5 MBytes/s) with 15 threads but Rclone isn't?
As I wrote all my files have size no more than 3 MB. onedrive-chunk-size default value is 10 MB
