Synapse will handle it and handle it well.
That said, you need to have some knowledge of how threading works or you can
use methods such as the GroupCanRead method to detect if you need to service
a connection. Depending on the level of latency allowed , you may have to
use a combination of thread pools together with groupcanread.
I have created a IPC dispatch server using synapse that work quite well with
600-800 clients where i have a thread for every 50-100 (64 on win32)
connections that does groupcanread and passes the socket that need servicing
to a thread pool of 5-10 threads that will read and process the data and the
pass the messages to a send pool that will send the messages to which ever
connections that have subscribed to the message type in question.
My initial version was windows only and used IOCompletion ports, but as I
needed a more generic version for other platforms I needed to use more
traditional socket selects that synapse wraps nicely for you in the
groupcanread method.
