	Only used once, the 15 minutes directly after the software is installed.
	
	5 second rounds; Accelerated mode 
	Used 30 minutes directly after the software is restarted. (Also following Bootstrap mode) 
	15 second rounds; Normal mode 
	Default operation 
	60 second rounds; Slow mode 
	Entered when Tribler has been running for more than 24 hours
