I checked how long this takes, to ensure it isn't slowing the code down. It isn't. Even a little. At precision 10 there isn't even a difference.
Code used:

codeTimer.start()
codeTimer.start("update")
lightController.update() # Update the gui / physical leds
codeTimer.print("update")
codeTimer.print()

returned:

0.1769356728s since starting id: "update"
0.1769356728s since starting id: "current"
