Qt for a high performance server

  • Hi
    I am developing a Qt mobile application which connects to a server which does some heavy duty processing. I dont use HTTP but just send JSON objects back and forth using simple TCP. Now I used TCPServer and implemented a neat multithreaded application that acts as the server. Normally one would use PHP or Java servelets to do this but I took this route and ended up with a "C++ server" which I think is very very rare. But enjoyed being able to use C++ and OOP instead of a scripting environment.

    My question is, is this a recommended route ? What if I have thousands of users connecting to the server per second, does the TCPServer, QNetworkAccessManager and QThread infrastructure scale up and handle this load? Or does it end up similar to a standard web server and its limitations (if well written using threadpools etc) ?

    Hi and welcome to devnet,

    The only answer I see is: benchmark. You have to test your server under heavy load to see how well it's doing.
