Better performance with Erlang multisend?

[benbro]

There is a discussion and PR for multisend support - being able to send the same message to many pids. Might help with MUC for broadcasting the same message to many clients in a large chat room. Do you think it is relevant?

I think we do privacy check for each user before broadcasting + some extra outing logic. So, it could be potentially tricky to add, especially into muclight.

Hey there,

We're closing this issue mostly because Erlang multisend is not existing yet (and I was the one working on it for a while btw!), but also, because the topic is a lot more complicated depending on the use cases. Some, like MUC broadcasting, aren't directly a good fit because as mentioned by @arcusfelis, you need to do things like privacy checks and other routing logic.

I do however want to take advantage of such a multisend when it is finally made available, but that'll be a whole epic on its own and the time ain't there just yet :)
