Was that 310 milliseconds in Perl?

One thing that may affect the Java performance when written out to the
screen is the overhead of using System.out.println() calls as these are a
call to native code and synchronized too for multithreaded output.

Maybe if we can pump the test through a profiler and work out where the bulk
of the Java operations are occurring for test 1.
