servicestack app host vs iis for high performance REST service

Question

as servicestack leave it open to host service in web server or in stand alone app.

What is the best in term of performance both raw and for a high number of clients ?

Hosting on apache or nginx or XSP or IIS is just for added functionality or for perf ?

Answer 1

servicestack.net itself runs on Ubuntu / Nginx + MonoFastCGI, although we've been notified others have been able to get better performance with self-hosting which you can still serve behind a Nginx/Apache reverse proxy if you still wanted access to a full-featured web server.

You can also wrap a self-hosted ServiceStack in a Linux Daemon.
