I have paint application, in which the server sends the co-ordinates to a set of clients. I use the above code for sending, launching on a separate thread. This sends data to each client sequentially. This will cause a delay to the clients at the end of the list. Launching a separate thread for each client has scalability issues. Is there is scalabe way to write the above code maybe using async.io?
