So what happens on the drive side if I have MPX set to 3 and then start a backup of 2 clients that can push data fast and 1 client that are really slow?
Is it the slow client that decide the speed of the drive then and make it stop/rewind/paus etc. and the other clients have to wait for the slower one?
