repeat(1000) { loadAndCombine() }

will take 1000 seconds

repeat(1000) { launch { loadAndCombine() }}

will take 1 second my question is whether wrapping it with

launch

is the “correct” way of doing this

Correct if you don't need result or operation

great! thanks @gildor, I guess i can use async, await/awaitall if i need results

and if you want to run them in concurrently, yes. Otherwise use withContext or suspend functions without wrappers
