from as little coding experience i have i can say that I have seen blazingly fast V1.0 of applications which doomed to sluggish responses because of poor maintenance. So, i really don't buy the speed thing. I'll always design with a note that "There will be no awesome-coders to maintain this". A well-maintained version of Java app will beat a struggling C app anyday. So, i differ. And, ofcourse if you know what you are doing, these graphs do make sense and its worth an effort to dig out the flipping bits on registers.
"A well-maintained version of Java app will beat a struggling C app anyday."
And a poorly maintained C program will outperform an equally poorly maintained Java program...
The things that make programs dramatically slower is poor algorithmic complexity (and often a poor understanding of the architecture, be it the JVM or the metal). That's not what we're talking about here though, this discussion is pretty explicitly about start-up times. We're talking constant-time issues.

And luckily the crappy java programmers will never even get a C program of any complexity to start up.
