The Tcp server need to serve many clients, If one client one server port and one server thread to listen the port, I want to know weather it is faster ?
If one port is good, could someone explain the different between one port and multiple ports in this case, thanks!
Generally speaking* the server will allocate it’s own outgoing sockets for each connected client (and you don’t need to be aware of those numbers). Each client connection handle will hold it’s port references.
When defining the servers connection port, you will allocate a socket for incoming clients to connect to. There is no performance benefit using multiple sockets, in fact allocating additional sockets will show a performance hit (although for each port it will be tiny.)
update…
By the way, assigning multiple incoming ports (particularly a large range) for clients to connect to is also insane. From the perspective of making the service usable and maintainable.
