[OS X TeX] Mulicores?

[Murray Eisenberg]

Given that a complete pdflatexmk run takes several minutes on my iMac, timing with sufficient precision is easy: 

	(1) run the following shell file “now.sh””

		#! /bin/bash
		today=$(date +%Y-%m-%d_%H-%M-%S)
		echo $today% 

	(2) immediately press the TeXShop Typeset button

	(3) as soon as I see in the console that execution of pdflatexmk has completed, run that same shell command again

	(4) subtract the time given by (1) from the time given by (3)
