Inside boost::concurrent_flat_map
gtl library author here. Very nice writeup! Reading it made me think, and I believe I know why gtl::parallel_flat_hash_map performs comparatively worse for high-skew scenarios (just pushed a fix in gtl).

Boost 1.81 will have boost::unordered_flat_map...
I do this as well in my phmap and gtl implementations. It makes the tables look worse in benchmarks like the above, but prevents really bad surprises occasionally.

Comprehensive C++ Hashmap Benchmarks 2022
Thanks a lot for the great benchmark, Martin. Glad you used different hash functions, because I do sacrifice some speed to make sure that the performance of my hash maps doesn't degrade drastically with poor hash functions. Happy to see that my phmap and gtl (the C++20 version) performed well.

It is now trivial to cache pure functions with highly efficient, concurrent cache.
This is very easy to do with the latest version of gtl. And it is extremely efficient, as the caching mechanism uses the parallel hashmap, which internally is divided into N submaps each with its own mutex, reducing mutex contention to a minimum.

Updating map_benchmarks: Send your hashmaps!
AFAIK sparsepp has been dropped entirely in favor of the containers in GTL: https://github.com/greg7mdp/gtl
