Speed up time machine backup on MAC

The time machine backup runs in the background and is programmed to not take much CPU power in order to not influence the normal work. But sometimes it is necessary to have the backup done in the fastest way possible (i.e. after backing up to a new hard drive). The following command:

sudo sysctl debug.lowpri_throttle_enabled=0

gives back the normal priority to the time machine backup which speeds up heavily the copy process.

This parameter is being reset to the original value 1 after a reboot.
