Java Performance Testing

    This article describes attempts to determine whether it is beneficial to upgrade from Java 7 to 8 from a purely performance view.  I also figure out which machines and OS's are best at the task.  So far all my Apple Mac machines seem to do BigInteger benchmarks faster.

Machine and Java Version Baseline

    The following table sets a baseline based on machine type and java version (6/7/8) - for single threaded performance
