> If you don't have reproducible, fair benchmarking, you can be blinded by your own hubris. Our contributors and maintainers depend on benchmarks to ensure that as we strive to improve TiDB, we don't negatively impact its performance. To us, not having benchmarks is like not having logging or metrics.
