This entire benchmark is frankly a joke. As other commenters have pointed out, the compiler flags make no sense, they use pretty egregious ways to measure performance, and ancient versions are being used across the board. Worst of all, the code quality in each sample is extremely variable and some are _really_ bad.

I mean this is only meant to be an iteration if I understand correctly. Its not like someone is going around citing this benchmark yelling rewrite everything in Julia / D. Imo this is a good starting point if you are doubtful or fall into the trap of Java is not fast. For most workloads we can clearly see, Java trades off the control of C++ for "about the same speed" and much much larger and well managed ecosystem. (Except for the other day, when someones OpenJDK PR was left hanging for a month which I am not sure why).

Quality does vary wildly because the languages vary wildly in terms of language constructs and standard libraries. Proficiency in every.single.language. used in the benchmark perhaps should not be taken for granted.

But it is an GitHub repository and the repository owner appears to accept PR's and allows people to raise an issue to provide their feedback, or… it can be forked and improved upon. Feel free to jump in and contribute to make it a better benchmark that will not be «frankly a joke» or «_really_ bad».

		I'm completely alright with just having fun and hosting your own little sandboxes online, but what good does it do to post and share this with others in its current state? The picture it paints is certainly not representative, and this sort of thing has been done a million times over with much better consistency. Again, I think it's great to hack around in every language and document your journey all the way, but sharing this is borderline misinformation. It's certainly not my duty to right the wrongs of this benchmark.
