> DiskANN is known to be slower at indexing than HNSW I don't remember the numbers here, maybe 10% slower? It wasn't material enough to make me worry about it. (This is with using an HNSW-style incremental build, not the two-pass build described in the paper.) > and the blog post does not compare single threaded index times with Lucene. It was about 30% worse several months ago with my concurrent hnsw patch, should be significantly improved now since JVector (1) doesn't need the CompletionTracker to keep the layers consistent, b/c it's single layer, (2) added a DenseIntMap concurrent collection to replace ConcurrentHashMap for the nodes. -- This is an automated message from the Apache Git Service.
