This document discusses why bad mobile app performance is common and how to improve it. It notes that consumers now expect instant gratification and connectivity, so performance is critical to customer experience. Poor performance can negatively impact sales, satisfaction and revenue. Issues often stem from inefficient code, poor caching, high latency or slow rendering. To transform, companies should adopt a performance engineering approach using tools that integrate monitoring across the entire technology stack from mobile to cloud. This allows optimizing apps based on real user data to improve the customer experience.
