Question : C++ Speed Versus Java

Hi,

I am trying to understand in what circumstances, if any, C++ is significantly faster than java.  I wrote a Java program that used an iterative method to find a solution to a simple game, and then I tried rewriting the program in C++, expecting to see significant speed increases.  However, the speeds were very close, and in fact the Java program was a tad faster.

I can post the code from both programs if anyone needs that info to answer the question, but I just wanted to start by getting general info about the speed differences between the two languages.  I am specifically interested in iterative simulations... specifically, using fictitious play to solve for nash equlibriums.  

Thanks for any thoughts,
Jonah
