> Almost 10x indexing throughput improvement tells me we are doing something silly in Lucene. I did not test this specific integration but Faiss is multithreaded on bulk training, adding and searching so we have to be careful when comparing the result. The benchmark results show a single segment but only Faiss reports time spent in the force merge. Does that mean that you indexed with `-numIndexThreads=1` for the Lucene run? Since Faiss uses multithreading by default, we cannot compare with Lucene if we don't use multi thread indexing and merging. -- This is an automated message from the Apache Git Service.
