Abstract

For several years WhatsApp has been one of the most popular Android apps in the world and a lot of this success stems from how performant and reliable it has been, especially in older phones. This session describes the philosophy of "Performance by Construction" and our efforts to keep the application and codebase simple, small and reliable. We'll discuss choices and tradeoffs that we've made at the architectural level to prevent regressions, ways that we found to optimize efficiency and make our apps work at the scale of billions of active users.
