rclone test speed

Run a speed test to the remote

Synopsis

Run a speed test to the remote.

This command runs a series of uploads and downloads to the remote, measuring
and printing the speed of each test using varying file sizes and numbers of
files.

Test time can be innaccurate with small file caps and large files. As it
uses the results of an initial test to determine how many files to use in
each subsequent test.

It is recommended to use -q flag for a simpler output. e.g.:

    rlone test speed remote: -q

**NB** This command will create and delete files on the remote in a randomly
named directory which should be tidied up after.

You can use the --json flag to only print the results in JSON format.
