Afaik one of the downsides in computationally expensive tasks is because of immutable data. For certain problems there simply are more performant algorithms around for mutable data then you have for immutable data. Sometimes you can mimic those by using ets, which is an in memory database within the beam (so mutable), but I’m not sure what the determining factors are for when this works or not.
