06/04/2021, 8:31 PMI have a Compose view that scrolls with maybe 56 ‘subviews’ and performance is not good. I know the Compose team is still working on optimization, but is there anything I can do to measure performance or provide info to the team to assist? I tried using the latest layout inspector, but it just crashes the app. Thanks.

I have happily coded my whole app in compose only to find out that on weaker phones it lags like hell. I mean scrolling of accompanist Pager and LazyColumn with many items are really slow.
