Linux Apache Perfork Set process number of responses

Linux 7.5GiB memory, 4 EC2 Compute units (2 virtual cores, each with 2 EC2 compute units), 850GB Local instance storage, 64-bit platform
Apache2.2 PHP5.3 mysql connected remote database server
Google Analytics Real-time detection shows basic simultaneous 500, 600, 700 to 1000 multiplayer online

Maxspareservers 40
Serverlimit 10000

Top shows a bunch of httpd processes,
Problem:
Perfork inside of Startservers, Minspareservers, Maxspareservers, Serverlimit, maxclients, maxrequestsperchild what mean Ah, Which control the number of simultaneous responses Ah, the number of processes, the number of sub-processes, top display of each httpd a process or a child process? , Perfork set What's the problem no,, Apache settings also need to pay attention to what?
