# compose

So I have a calendar built via LazyColumn and have been trying to optimize it. Made some good gains by using the metrics compiler outputs as guidance. I am down to what appears to be modifier aggregation. Is there a built in way to have the column throttle how many items it attempts to do per thread frame?

One thing you could try doing is `remember`ing big modifier chains, but i don’t know if that will help with materialization
just be mindful of dependencies – if you’re passing values into modifiers, if they’re not backed by states they should probably also be keys on the remember

Yes that will for sure be the case here. its just a bucket of booleans for what the modifier config will be. I'll prob just do a quick data class to make things explicit and the remember block more simple

If each calendar item is clickable, note there is active work to make clickables less expensive in upstream compose. That would help a bit here.

yeah they are almost all clickable. hard to know which modifiers are the culprit from the signatures in the flame charts though so I didn't assume it was one or the other. I've got it sped up to the point that only first load has a bit of jank. good enough for now.
