How We Cut React Native Cold Start from 1.78 s to 0.8 s: A Four‑Step Optimization Journey

This article details a systematic four‑phase optimization of React Native page startup—preloading resources, advancing initialization, reusing and pre‑creating containers—that shrank cold start time by 55 % (1.78 s → 0.80 s) and hot start time by 70 % (1.10 s → 0.33 s), while exposing the new pitfalls introduced by container reuse.
