Yeah, I am aware of that fact. I also expected someone would say Azureus (now called Vuze). But if you check out the peers in your torrent client, you will see that the majority of users use utorrent. Anyways it's not just about torrent client (which is not a too complicated piece of software) but other kinds of desktop and server applications, that are required to have low latency and small footprint. Rhetorical question: why all major browsers are written in C/C++? Don't get me wrong, I like dynamic languages, currently I am working in python (besides C++), but the main advantage for me in those languages are rapid prototyping/development and lots of built in libraries, not the performance.
