nginx reads request from client to a big buffer, then connect to a free fastcgi server process, sent the whole buffer to it. Then, fastcgi process queries the database in a very short time, and send the result to a buffer of nginx, then go on sleeping. Actually, the time of a cycle of fastcgi working should be as short as possible.
