  • What do errors in your diagram represent? I find it confusing to have arrows going from a component to an actor. Commented Apr 11, 2021 at 19:58
  • the system works as expected, but we can't scale up to support a large amount the clients due to each client currently has one thread to serve them. The actor is our client to request streaming live data from us. our system is a data distribution system. Commented Apr 11, 2021 at 20:39
  • Sorry that was hasty typing, I meant to ask "what do arrows" represent? I guess it is flow of data? I usually read/write diagrams the other way around with the user on the left and data sources on the right. But I guess that is just a different convention. Though I think your diagram would benefit from labeling the arrows or having a legend. Commented Apr 11, 2021 at 20:42
  • Also: How are messages dispatched in Step B? Is there usually one message per user, or all messages go to all users? Or every message goes to different sets of users? Commented Apr 11, 2021 at 20:45
  • Too little info for me. Profiling seems to have been done. Load testing with varying dummy data hopefully too. Sometimes one can change the granularity of concurrency: larger/smaller pieces per thread, or defer some costly operations to a later point. There are others more experienced than me.
