My primary goal with the benchmarks I run has been to identify performance regressions, especially ones that can be fixed to make open source databases better. And so I focus on comparing old and new versions of one DBMS at a time to identify where things get better or worse. But here I compare Postgres with MySQL (InnoDB & MyRocks) to show that neither is the best for the Insert Benchmark — all are good, but none are perfect.The per-DBMS results are here for Postgres, InnoDB and MyRocks. Those posts also have links to the configurations and builds that I… Read more

While trying to explain a Postgres performance problem I repeated the Insert Benchmark on a small server for MyRocks from MySQL 5.6 and 8.0. This post explains those results. The previous report for a cached workload is here.tl;drDisclaimersThe low-concurrency results here are worse than the results from a bigger server with more concurrency because the result here depends more on CPU overheads and MySQL keeps on growing code paths, while on the bigger server the cost from new CPU overheads is offset by other improvements.Some of the regressions here are similar to what I measure for InnoDB and the problem… Read more

Last year I spent much time trying to tune the Postgres configs I use to improve results for the Insert Benchmark. While this was a good education for me I wasn't able to get significant improvements. After writing about another perf problem with Postgres (optimizer spends too much time on DELETE statements in a special circumstance) I revisited the tuning but didn't make things significantly better.The results here are from Postgres 16.2 and a small server (8 CPU cores) with a low concurrency workload. Previous benchmark reports for Postgres on this setup are here for cached and IO-bound runs.tl;drI have… Read more
