However, it lacks the newer Boost stuff which is very fast.
The Hopscotch map was interesting at the time but due to unfortunate timing was immediately outshone by absl::unordered_flat_map A.K.A. "Swiss tables", and there's been even more water under the bridge since then.
How does it compare to boost unordered flat map?
Looks like the benchmarks were last updated in 2019.

Has some older benchmarks, including those two.
A more recent benchmark is https://martin.ankerl.com/2022/08/27/hashmap-bench-01/
