 megabytes, while 'g' or 'G' makes it gigabytes. The suffixes (k, M, G, T, P)

+The rate limiting logic works on averaging the transfer speed to no more than
+the set threshold over a period of multiple seconds.

 If you also use the --speed-limit option, that option will take precedence and
 might cripple the rate-limiting slightly, to help keeping the speed-limit
 logic working.
