true.

but the implementation for a bubblesort is relatively simple and the c++ and
java code match each other very very closely (i.e 2 simple for loops and a
swap). Let me know if you want the codes that i used. Naturally we only
started the timing when after the arrays were initialized.

I was also surprised with the difference in times for different jvm
implementations. (an order of magnitude of 6!). I retested numerous times to
make sure that I wasn't making a mistake. The compiler makes a difference
too. When I compiled with the BEA 1.5 and ran using the Sun 1.6, I got a
slower time (13 s) than if I compiled and ran using the Sun 1.6 (5s). 
approx 3x as fast.

I'll probably be making a few more of these tests and perhaps post the
results online sometime.

Of course it's a little too presumptuous to make any conclusions at this
point, but I was wondering whether it would indeed be more beneficial to
just simply upgrade to a higher version jvm (if possible) to improve
performance rather than going through our codes with a fine tooth comb.
