    The Great Database Performance Showdown

    0:00

    Imagine staring at a monitoring dashboard painted entirely red because your database hit a performance cliff during a simple reporting task. Many developers choose MongoDB for its "vibes-based" flexibility, but as of 2026, the gap has collapsed. In a test of one million rows, PostgreSQL 17 handles complex analytical aggregations nearly three times faster than MongoDB 8.0. While Mongo still wins on bulk document inserts, Postgres now bridges the gap with its JSONB type, giving you relational integrity and document flexibility in one engine. We’re breaking down which side of the 1M ops test your web app falls on.
