> As can be seen from the comparison, there is very slight change that the hierarchy brings: a small increase in recall by at the expense of lower QPSs It looks like QPS is sometimes worse, but often better (like in all the sift-128-euclidean runs, num_cands >=50). I wonder if the first runs are affected by a lack of warm-up? My original set-up you linked to didn't include a warm-up, and in LUCENE-9937 we found that this can have a big impact on the first runs. -- This is an automated message from the Apache Git Service.
