requests without consuming a separate thread.
the new async behavior in Servlet 3.0 is not related to the underlying IO technology. It has nothing to do with NIO or blocking IO. We should be able to implement it using BIO without any issues, since its not IO bound.

2- if the request chain to filter :-
when a connection is idle between requests , the thread is still allocated to the 
particular request since the servlet 3.0 specification says :"A Filter and the 
target servlet or resource at the end of the filter chain must execute in the same 
invocation thread"
It is look like thread per connection.

if that is false what do you understand from this sentence :"A Filter and the target servlet or resource at the end of the filter chain must execute in the same invocation thread" ??

Tomcat"
