Spring MVC performance with embedded Netty

I know Netty is very fast based on NIO. According to google research, there are many good characteristics for a wide variety of protocols.

But I am really wondering how to apply it to a web application. I found some really interesting examples, for example:

Combine Netty and Spring MVC

and a really good example is here .

It looks like it makes sense to use it for a web application, but I can't seem to find a Google performance result for Spring MVC based on the embedded Netty server.

I know twitter and other world famous projects use it, many of them just because of jdk 1.6 improvements, for their own implementation of ByteBuffer and so on, but I don't know about their netty usage for a web application.

My questions:

1) Does anyone know one of the good examples of using netty to implement the HTTP protocol.

2) Does anyone consider the performance for this?
