I quoted Abel out of context deliberately, to make the point that
comparing performance of different processors isn't a simple process.

The cost of the JVM start-up cannot be eliminated, but it can be
amortised. For a fair comparison, you need to know what this overhead
is, so you can make sensible judgements.

The only real sage comparisons are on your own data on your own
machine. But benchmarks can be useful provided sufficient data is
presented with the results.
