11/30/2020, 4:20 PMHas compose gone through performance optimization yet? I found someone who made a small compose benchmark vs standard Android views a while back. His results shows compose running more than 50% slower than Android Views. I updated his benchmark to the latest version of compose, and ran it. I haven’t seen any numbers, but compose is noticeably slower from a user perspective of loading the page. https://github.com/MustafaBasim/uiPerformanceTests

For the most part as long as you’re getting 60 FPS it doesn’t really matter but we do pay a cost for the brilliant abstraction layer that compose provides.
