The Threads iOS team has managed to maintain app performance, despite its significant growth.
The article provides insights into the key metrics that Threads monitors to ensure good performance.
These metrics include %FIRE (percentage of people who experience a frustrating image-render experience) and Time-to-network content (TTNC).
The Threads team has spent a lot of time removing unnecessary code and graphic assets from their app bundle to reduce their app's binary size and enhance performance.
The team has also developed a new tool called SLATE, which measures navigation latency efficiently and helps analyze how new features impact performance.
The article also covers different strategies that the team used to improve their app's performance and resiliency, including Drafts and reducing the perceived latency of text posts.
Threads also adopted Swift concurrency, which improved their code's stability and performance.
The team will continue to monitor their key metrics and iterate on their tools and strategies to improve the app's performance in the future.
Users can also contribute to improving the app by submitting bug reports.
