The [current results](https://versions-benchmark.lmdbjava.org/) show significant write performance regression after release 0.8.3.\n\nI subsequently developed an automated bisection capability in the [LmdbJava Benchmarks](https://github.com/lmdbjava/benchmarks/) project. This identified the regression:\n\n```\n\n  Commit   Date                    Score    Change     Message\n========================================================================================================================\n   be2a15b  2023-02-04 00:28:16     89.07             [maven-release-plugin] prepare release lmdbjava-0.8.3\n   1cc7e6c  2023-12-04 07:42:08     94.49     +6.09%  Test on Java 21\n   f17b63f  2023-12-05 01:34:17     91.57     -3.09%  [maven-release-plugin] prepare release lmdbjava-0.9.0\n   b5dfb25  2025-02-16 23:37:16     91.38     -0.21%  Uplift lmdb from 0.9.29 to 0.9.31 (#245)\n * 68f0a44  2025-02-16 23:46:30    128.63    +40.76%  Add DbiFlags#MDB_UNSIGNEDKEY to allow to compare byte array, Byt...\n   928cf7b  2025-02-20 01:26:13    129.12     +0.38%  Add url element to pom.xml to satisfy OSSRH deployment rules\n   dc24f4b  2025-10-31 00:20:59    122.03     -5.49%  Generalise benchmark link\n```\n\nThe regression emerged in commit 68f0a44, which modifies comparator logic. This represents a 40.76% write performance degradation from the previous commit.\n\nGiven @at055612 is undertaking significant comparator changes in #249 and #250, this regression is likely to be addressed in that work. The bisection tooling is now available to verify performance impact of changes.\n","author":{"url":"https://github.com/bp-alex","@type":"Person","name":"bp-alex"},"datePublished":"2025-11-03T03:23:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/268/lmdbjava/issues/268"}
