The blog post provides a detailed guide on conducting a performance testing experiment using the SQLite Trek app and DevCycle's feature flag capabilities. It illustrates setting up feature flags to dynamically assign users to one of three database solutions—SQLite (local), Turso, and SQLiteCloud—allowing for a controlled comparison of their query response times. The post outlines prerequisites such as setting up database structures and configuring the DevCycle platform, followed by instructions on creating and running the experiment using Express and tinyhttp frameworks. The experiment involves user queries being distributed across the databases, with response times tracked and visualized via DevCycle. The guide also discusses expanding the experiment globally for a more comprehensive performance analysis and delves into further exploration of DevCycle's experimentation features for optimizing performance and testing new features.
