Baseline Profiles

Meta has integrated Android’s Baseline Profiles into its applications, resulting in performance enhancements of up to 40% across critical metrics. The Baseline Profiles, created from user data, allow developers to optimize app performance by controlling which classes and methods are included for install-time optimizations. Meta has established a robust infrastructure for profile-guided compiler and runtime optimizations, focusing on improving cold start performance and user interactions. The implementation of Baseline Profiles has led to significant improvements in app startup times, scrolling performance, and navigation latency.
