OK last night's run was fully updated packages/kernel/java/lucene, and I fixed the memory clock misconfiguration. Now many tasks are faster than before! See [`CountOrHighHigh`](https://benchmarks.mikemccandless.com/CountOrHighHigh.html), [`AndHighMed`](https://benchmarks.mikemccandless.com/AndHighMed.html). I think the gains are mostly due to fixing memory speed from 2400 MHz (all these years... sheesh...) -> 3200 MHz spec, but maybe also BIOS upgrade enabled Linux `performance` CPU governor to run things hotter/faster/closer-to-knife's-edge -- what a complicated Linux subsystem). Oddly, vector indexing performance is still down: [`medium vectors indexing time`](https://benchmarks.mikemccandless.com/indexing.html#MedVectorsIndexTime) and [`knnPerfTest.py` indexing throughput](https://benchmarks.mikemccandless.com/knnResults.html#knn_indexing_docs_per_sec). I would have expected these to see big gains with faster memory bus, especially, since it's moving all those vectors. I'll try to get to the bottom of that. -- This is an automated message from the Apache Git Service.
