    Kris, how well does the Deltachat server scale in terms of users, rooms, number of participants, amount of messages exchanged, etc.?

  2. Link Mauve

    Mostly compared to Prosody or Ejabberd.

  3. Kris

    the issue with DeltaChat and group-chats isn't that.

  4. Kris

    the issue is that it doesn't really have a concept of group-chats, but just pretends so by basically emailing everyone in CC.

  5. Kris

    so it is up to every individual client to make sure they send messages to all participants, and split brain group-chats can easily happen

  6. Kris

    on small private group-chats that isn't a problem, but I find it a bit misleading that DeltaChat proponents claim that they can do group-chats with 1000 participants with no problem.

  7. Kris

    under ideal simulated conditions maybe

  8. Link Mauve

    So it scales extremely badly for vanstabholme’s usecase, gotcha.
