It will be hard to make a final conclusion. It is more of a research exercise to learn. All we can say is that as the code stands right now Java JIT is faster than C++ clang AOT for this simple map implementation. And all the code, compilation scripts, executions scripts, details, etc. are available in our GitHub so that other people can execute and play with these benchmarks in their own environment, to draw their own conclusions.

There is also an ongoing discussion on SO => https://stackoverflow.com/questions/79268109/c-implementatio...
