Improving Threads' iOS Performance at Meta
Briefly

Meta engineers, Dave LaMacchia and Jason Patterson, emphasize that an app's performance is crucial for user retention, necessitating speed, efficiency, and reliability across devices.
To optimize Threads, engineers focus on metrics like FIRE, which tracks users leaving before images render, ensuring they catch any regressions in image loading.
TTNC, or time-to-network content, measures how quickly the app launches and displays user feeds; reducing binary size is essential to improve overall performance.
A/B tests indicated that even slight navigation latencies could diminish user engagement, showing that performance issues significantly affect how users interact with the app.
