I'll give it a try once 1.9.12 is out. AFAIK uWSGI is blocking and this is the cause of offload threads, this is fine for dynamic requests that needs to run app code, but it also means that uWSGI will probably do worse that lighttpd or nginx in real world contest with serving static files under a lot of load and few thousands client connections. AFAIK both lighttpd and nginx are asynchronous. It isn't big issue since we can put uWSGI behind nginx and use it only for non-static requests, but since HTTP frontend is getting more features I wonder what's the goal here, is uWSGI intended to be as fast as others (or maybe it is already), or nginx will always be required when maximum possible performance is required?
