in my forums we started a thread collecting how long people's Arduino IDE takes to start up (which they posted to various places).
You're welcome to post there (you should register and then make a sweet table summarizing your stats so we can compare).
of course, you can do it here too :-D
NOTE: this question is in bar sports because it has absolutely no redeeming value. it doesn't matter in the slightest whether the java runtime starts in 2.4 seconds or 11 seconds. the only question is: How bored are you? :D :D :D :D
