JIT is the key to a lot of that. Performance depends greatly on
the compiler, the JVM, the algorithm, etc.

I won a bet once from a friend. We wrote comparable programs in
Java and C++ (some arbitrary math in a loop running a bazillion
times).

With defaults on both compiles, the Java was actually *faster*
than the C++. Even I didn't expect that. But as I said, this
sort of thing is highly dependent on many different factors.
