An inquiry into nondogmatic software development. An experiment showing double performance of the code running on JVM comparing to equivalent native C code.
This pull request is to show how moving to a more traditional [xorshift RNG](https://en.wikipedia.org/wiki/Xorshift) can result in massive speedups as well as more consistent results across languages as it doesn't...
malloc()
I think the problem lies in the fact that the C code is using `malloc()` (a lot). Which is not exactly as "performant" as the `new ...` in Java. For...
P=NP
"It seems that the code executing on VM can be actually much faster than the native one thanks to technologies like HotSpot" Execute VM inside a VM, then repeat arbitrary...
This sort of benchmarking is always super fascinating. But, putting the numbers into a chart would really tell the story.
