But for a good chunk of software engineers AFAIK compiling Java to bytecode and running it on the JVM easily outperforms their optimized code performance wise in most cases. JVM and JDK writers (and the same people on the Dotnet side) aren't dimwits and their efforts over the last two decades are being applied every time we compile and run software on their platforms.
