Create a github repo, so everyone can run the benchmark, ... and fix it?

Nice idea! It also should contain memory measurements and feature matrix (as feature set can affect speed).

It also would be nice to have benchmarks on some different key/value types or sizes, like class as key or value, struct(fat struct) as key or value, etc..

Hmm, thank you for that. We are using extensively internally and have not had segfault. Can you share the benchmarking code?

I will of course update the readme to include the omitted function call ();

This reinforces my increasing conviction that referentiability-by-default is on a level with nullability-by-default and mutability-by-default in the "Great Collection of C-Derived Language Design Errors".

I added benchmark folder to my project

https://github.com/ikod/ikod-containers/tree/master/bench

Please add your implementations

Thanks!
