tl;dr:We wanted to improve the coding experience for our development teams through infrastructure changes. We conducted research among 318 engineers and learned that: (1) Developer productivity and satisfaction were compromised due to longer build times, as per our Engineering Satisfaction survey results. (2) Build times on Apple silicon machines were 43% faster than Intel-based Mac systems, overall, and up to 50% faster for Android builds and 40% faster for iOS builds. And more.
