This has results from sysbench on a small server with Postgres versions 12 through 19 beta1. Sysbench is run with high concurrency (40 connections) and a cached database. The purpose is to search for changes in performance.Postgres remains
This has results for Postgres versions 19 beta1, 18.4 and 17.10 with the Insert Benchmark on a small server using a cached and CPU-bound workload. I also used MySQL 8.4.8 to see where performance was different.Postgres continues to be borin…
This has results for HammerDB tproc-c on a large server using MySQL and Postgres. I am new to HammerDB and still figuring out how to explain and present results so I will keep this simple and just share graphs without explaining the results…
This has results for modern Postgres and MySQL using write-heavy tests from sysbench and a large server. I think there are regressions in Postgres that arrive in some of versions 16, 17, 18 and 19 beta1 but I am far from certain and this bl…
This has results for Postgres versions 19 beta1, 18.4 and 17.10 with the Insert Benchmark on a small server using a cached and CPU-bound workload.Postgres continues to be boring in a good way. It is hard to find performance regressions. tl;…
This has results from sysbench on a small server with Postgres 19 beta1, 18.4 and 17.10. Sysbench is run with low concurrency (1 thread) and a cached database. The purpose is to search for changes in performance, often from new CPU overhead…
This has results from sysbench on a small server with MySQL 9.7.0 and 8.4.8. Sysbench is run with low concurrency (1 thread) and a cached database. The purpose is to search for changes in performance, often from new CPU overheads.I tested M…
This post provides another way to see the performance regressions in MySQL from versions 5.6 to 9.7. It complements what I shared in a recent post. The workload here is cached by InnoDB and my focus is on regressions from new CPU overheads.…
This has results for MariaDB versions 10.2 through 13.0 vs the Insert Benchmark on a 32-core server. The goal is to see how performance changes over time to find regressions or highlight improvements. My previous post has results from a 24-…
This has results for MariaDB versions 10.2 through 13.0 vs the Insert Benchmark on a 24-core server. The goal is to see how performance changes over time to find regressions or highlight improvements.MariaDB 13.0.0 is faster than 10.2.30 on…
This has results for sysbench vs MariaDB on a small server. I repeated tests using the same charset (latin1) for all versions as explained here. In previous results I used a multi-byte charset for modern MariaDB (probably 11.4+) by mistake
This post has results for CPU-bound sysbench vs Postgres, MySQL and MariaDB on a large server using older and newer releases. The goal is to measure:how performance changes over time from old versions to new versionsperformance between mode…
