We have developed a Client-Server Chat Messenger using QTCPSocket / QTCPServer.

I would like to know how many clients can be handled by server ? ie. how many users able to login at same time. Also I would like to know about server's performance while number of clients get increased.

We have checked upto 100 users manually (by using 100 PC).we don't know how to check further.

If you know any tool to test the above,kindly share with me.

Thanks in advance.
