[2]Boot Chart for LInux is a simple way to automatically make a chart consisting of the applications your computer runs at boot, with the time it takes to load each app. Here is an example:
As you can see, my computer's boot time was 30 seconds. I can use that chart to see which applications take a lot of time to load and remove them if they aren't important, etc. If my computer's performance would have been like the 17,5 seconds of Matt Cutt's computer, I could have used it to brag, but I can't do it with my 30 seconds boot time :)
