I recently compared MariaDB, MySQL, and PostgreSQL using the real mpazari.com application. The goal was not to produce a synthetic database benchmark. I wanted to answer a more practical question: does MariaDB really have an advantage when an application sends many simple queries? This question came up after reading an argument that PostgreSQL is obviously faster than MySQL, but that MariaDB should be faster for applications with many simple queries, while PostgreSQL is probably better for complex joins. The suggestion was that a MariaDB versus PostgreSQL comparison would be more interesting than a PostgreSQL versus MySQL comparison. ...

From Spring Boot to Rust: Rewriting a Live Marketplace mpazari.com spent years on a legacy ASP.NET stack — the .aspx URLs still in the wild prove it. A recent Spring Boot rewrite replaced that engine, first as a JVM jar, then as a GraalVM native image to tame memory usage. The question that started this project: if we rewrote the whole application in Rust, what would we gain, what would we break, and how do we prove we broke nothing? This post covers the rewrite, the parity hunting, the server-side build/deploy pipeline, and the load test comparing all three runtimes on the same production box. ...
