If I have a LazyList with a column that contains several sub-items (e.g. inside a card). How can I optimize it such that the nested items arent recomposed all the time? Im seeing 3 recompositions each time the list is recomposed, taking up about 15 ms each; since Im also using a pager, the same process is repeated for pages to the left/right of the current one, effectively taking up 135 ms everytime the list recomposes.

What Ive tried:
• Marking the data with @Immutable
• Using `ReusableContent`/`key(x){}` around the column items

Have you tried a release build?

[Zoltan Demant]

@Colton Idle Yep, all of this is on a release build, R8 etc

Curious, how are you measuring the durations?

@Tash

val duration = measureTimeMillis {
    // Render stuff
}
