C++ vs. Java Performance

[manderson5192]

2) Interesting...On the USFIRST.org beta testing forums, team 67 posted this:

the almost-empty loops we've timed run about 50 times faster in C++ than in Java.

Is there really no noticeable performance hit?

...and a couple, related question:

4) How does the Java vision API compare to the C++ one? Is there a large speed difference?

5) After having beta tested in java, will your team use it this year?

6) When do you think everything will be released for us non-beta-testers?

Thanks again!
