Does

LazyColumn

measure the entire list on first composition, and only composes the visible items? Or is the measurement also only done for the visible items?

Last time I looked it only subcomposes the visible items, which means it can only measure them as well.

Looking at the profiler, I was able to optimize a bit. A lot of time was taken up by

rememberVectorPainter()

calls from an icon which was repeated many times. Replaced with one call for the whole list which helped a lot. Text layout also seems pretty heavy, I tried setting

softWrap

to false, which also helped a bit. Still slower than I'd like. Investigating further...
