     I think I am doing the same carefull analysis as you before 
starting to write an application.


     Note that, for the case of a web server, different groups have made 
different choices. AFAIK Apache runs one thread per client while Nginx 
uses epoll() to serve multiple clients per thread. Nginx has the 
reputation to have a much smaller footprint and to be faster.
