Java isn't fast, but is it fast enough that you aren't going to see a
big enough performance difference to justify not using it. The
difference should be much less than, say, the difference between
processor revisions, such as the equivalent of a 3700-3750 X2 running
your code instead of a 3800 X2.
The big differences come down to methodologies of how you use the code
and what factors change in the design as a result. Java used to be very
slow back in the 1.1-1.2 days, but nowadays, all the critical parts of
the code end up triggering the JIT compilers and those sections then run
a translated equivalent in native code.
