Monitoring numeric variables over a network

Thanks a lot!

What is the speed (bytes per second) that shared variables can handle over a network?

Whatever your network infrastructure can support minus overhead for the shared variable protocol. That overhead isn't that huge but it is there and the connectionless nature of shared variables makes them not suited if you need fast command response times. So far it looks like you only have unidirectional dataflow from your clients to the server, so that should be not really the problem.

4 clients with 15 variables each once per second should be nowhere near the llimits of what shared variables can do. I suspect some serious architectural problems in your application.

Thanks for replying.

I have a question here.

PC Client write variables to PC Server.

So the PC Client performance is not linked to the number of clients in the system right?

The onle performance that can be decreased is the PC Server executable (the more clients there are less performance PC Serves has) right?

That point is important to me, because it does not matter if the performance of the server goes down but I do not want to lower the performance of the clients.

Thank a lot.
