[Mono-dev] Why not build official site on ASP.NET? Mono should enhance server performance and stability!

[Alan McGovern]

Just to add, while MonoTorrent doesn't use it's on threadpool, it doesn't
hog ThreadPool threads by blocking inside the async callbacks. As soon as a
message is received and my callback is invoked, I queue the message to be
processed and allow thread to return to the ThreadPool. As such, even with a
large number of actively transferring connections (> 50) I only need a
handful of threadpool threads. If you starve the threadpool, your
performance will suffer accordingly ;)
