Thanks joshua.lapacik@mongodb.com for the efforts and providing the flame graphs. I think we should close this one out as "not worth it". I just found the test file: https://github.com/mongodb/mongo-perf/blob/79cc3c7e00dda5590c1806aa40fd88bdea33e8b9/testcases/wildcard_index_query.js#L248
It looks like those tests are running with only 100 documents in the collection... what a weird test. I suspect this regression will improve on larger data sets and I think it is not that worthy of digging into. I'll add a quick note to the performance report and close this out. |
