> One of the Elasticsearch benchmarks detected a regression that is attributed to stored fields compression after moving to a 9.0 snapshot. I managed to isolate it to the change done on LUCENE-7521. It looks like LZ4 relied significantly on Direct16 for good performance, so replacing it with Packed64 degraded compression speed.
