Performance best practices for Jetpack Compose
summary
Advice for making Compose apps faster: always test in Release mode with R8 because debug disables optimizations; avoid expensive work during recomposition by using remember for sorting and supplying unique keys to LazyList; use derivedStateOf to collapse noisy state (e.g., show-button from firstVisibleIndex); defer reads into drawBehind to skip composition/layout; never perform backwards writes during composition; add baseline profiles via Macrobenchmark — jetsnack sees 22% faster startup, Google Maps 30%, Play Store 40% initial render.
