Benchmark results

This is the 2011 C++/Java/Scala/Go language benchmark of Robert Hundt, updated and rerun with the current versions of compilers.
Optimized versions of JVM languages (Java and Scala) take the lead in runtime speed while C++ (not optimized) still has the lowest memory consumption.
With the latest compiler, Go speed has greatly improved, while keeping memory usage to a modest level.
