    What kind of latency are you looking for?

    I doubt its expensive to query the database for messages since X ... once or three times a second ... "realtime" for humans :)

    In truth, all "events" are actually just variations of polling with different softwares doing the polling (OS...)

    See also Mojolicious: Websocket example under hypnotoad for similar discussion
