Fixing Performance Regressions Before they Happen

Fixing Performance Regressions Before they Happen

摘要

At Netflix we’re proud of our reliability and we want to keep it that way. To that end, it’s important that we prevent significant performance regressions from reaching the production app. Sluggish scrolling or late rendering is frustrating and triggers accidental navigations. Choppy playback makes watching a show less enjoyable. Any performance regression that makes it into a product release will degrade user experience, so the challenge is to detect and fix such regressions before they ship.

This post describes how the Netflix TVUI team implemented a robust strategy to quickly and easily detect performance anomalies before they are released — and often before they are even committed to the codebase.
