With the recent talk about Botmaker's old Java server and the SoulForge project trying to rewrite it all in C++, what kind of coding language would be the most optimum at handling the server with intense loads of data packets being sent back and forth (like in Prod)? Or is it not the use of coding languages, but the overall code structure that creates limitations on how much a teeny weeny wServer.exe can handle many instances of a whole Realm and many more dungeons?

I was curious because I had just read a few discussions about the server itself and not the content of it.
