How GitLab's QA Team Leverages Performance Testing Tools

This post introduces the GitLab Performance tool (GPT), a new open-source tool built on k6, designed for performance testing of GitLab environments. It details the setup of reference architectures and test data, the capabilities of GPT (broad test suite, customization options, sequential/selective test runs, enhanced reporting, built-in success thresholds), and how GPT is used in automated CI pipelines for daily/weekly feedback and release cycle comparisons. It also encourages external users to adopt GPT for their own environments.
