I tried another test: 1. knnGraphTest.py with -reindex and -stats (no searching) 2. knnGraphTest.py with no -reindex and -search With the idea that if there was some kind of OS paging thing it would affect this in the same way as the normal -reindex + -search, but it did not: I saw the latency improvement (around ~13 ms). So this makes me think something happens in the JVM that is doing the indexing that predisposes it to have worse search performance? Some kind of hotspot something or other? Next I want to try looking at profiler, but it is a bit tricky since the index + search profile is going to be muddied by the indexing part -- This is an automated message from the Apache Git Service.
