Benchmark

[Roedy Green]

People keep claiming Java is slow, quoting benchmarks from Java 1.1
era.

Two things have changed. Hotspot is faster and there are now static
native compilers.

Here in a benchmark on a project I am just completing. It is highly
CPU intensive spending most of its time in the BigInteger routines.

You are getting class load times included here.
