Hi!
The implementation of the HNSW algorithm in MariaDB is not identical to the paper (hence the m from modified or MariaDB in mHNSW).
You should not try to compare against equal M / ef_search values of other implementations, but rather compare QPS for a particular Recall target (say 95%, 98%, 99%)
That will give you an apples-to-apples comparison.

Thanks Sergei! Is it possible to let me know the internally decided ef_construction value? That will help me in putting recall results in context with other benchmarks. Is the ef_construction computed based on M / dimension etc?
