Hi. Performance testing in your CI/CD pipeline will catch performance regressions of what your team has covered with benchmarks or load tests. Anything else will fall through the cracks.
Even the most capable performance conscious teams in the world still have limited attention. Perfloop has been contributing significant performance improvements to the open source world too, across repos like ClickHouse, Prometheus, parquet-go, roaring bitmaps and more.

Yes! A typical use case is to efficiently implement ORDER BY LIMIT N in SQL databases in a way that doesn’t require sorting the entire column just to get those first N items.

Author here. Agree 100%! It's often what didn't work that is omitted. But there's so much juice in failed experiments — it's important to share with others.
