From latency to instant: Modernizing GitHub Issues navigation performance
The GitHub Issues team modernized navigation performance by implementing client-side caching, smart prefetching, and service workers. These techniques eliminated full page reloads, making navigation feel instant. The optimization reduced latency from seconds to near-zero, improving developer workflow efficiency. The changes are now live for all GitHub users, requiring no configuration changes. This update builds on previous performance work and leverages modern web capabilities to deliver a smoother experience.
