Java On Ryzen

Standard benchmarks you can find on the internet are of limited value when you use your machine for serious computations based on your own code. My machines often run for several days utilizing all available CPU cores, so performance is a serious issue, as is power consumption considering the insane power price we pay here in Germany. After AMD released the Ryzen processor I was quite disappointed by its multi threaded performance at my application. Recently I found out what was the source of the problem and that it can be solved.
