Has 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

I don’t think it’s ever possible to have a framework like compose, react, swiftui run faster than a well-optimized, imperatively written UI. 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.

I think what I noticed most of all is that even loading the screen took significantly longer.

Does adapterlist lazy load? Also how do the results look like without loading vectordrawables on the main thread?
I did not notice compose to be particularly slow
Also not that it is particularly fast

Might have to do with android views being bundled with the OS and therefore being well JITed.
