EM is certainly very fast but I don't know if it is easier to use. The  
documentation is hard to understand and the examples are all so  
simplistic it is often difficult to see how to write a complex client  
or server.

I suggest downloading projects that have used EM (like Thin) and  
learning good techniques from that code.
