If you are transferring large files over high-speed links and you have enough memory, then increasing this will speed up the transfers.
Rclone will automatically increase the chunk size when uploading a large file of known size to stay below the 10,000 chunks limit.
Increasing the chunk size decreases the accuracy of the progress statistics displayed with "-P" flag.
