I just ran the Tantivy benchmark (tantivy-search.github.io/bench/) on Lucene 10.2 vs a Lucene 10.3 snapshot build. Lucene 10.2 already performed very well, but Lucene 10.3 is on another level. Very exciting.

This small change yielded a ~5% speedup on several queries of Lucene's nightly benchmarks (see last data point at benchmarks.mikemccandless.com/OrStopWords....). Can you guess why?

Uwe now explains how Lucene takes advantage of the Panama foreign memory and vector support in spite of the fact that these features are still preview/incubating in the JDK

Guo Feng contributed a 2.5x (!) speedup to #Lucene's numeric range queries by using vectorization. HZ sped up query evaluation, ID sped up decoding data from the index. Lots of great performance improvements coming in Lucene 10.2.

Two good speedups on queries sorted by field on #Lucene's nightly benchmarks last night. This is due to a recent optimization to conjunctive queries being generalized to intersecting a query and a collector. github.com/apache/lucen...

Quizz: I'm working on a change that produces the following speedup when running the Lucene benchmark. Can you guess what the change does? I'll open a PR shortly.
