Yes, this is embarrassingly slow .so I solved your problem
the map member used for the lookups is a tsl::hopscotch_map (https://github.com/Tessil/hopscotch-map), which is a proper hash map. so it seems to be the latter, that the API is wrong, but from what I can tell it is only a wrongly named class. i don't see where the API makes guarantees about iteration order, which is where the implementation difference would be noticeable (beyond performance for lookup).

Any suggestions for resources to optimize for memory allocation/reallocation?
using an open-addressing hash table, such as abseil flat_hash_map or tessil/hopscotch-map
