I'm confused about the parameter in http{} , my example is here

[rollingsun]

this config is from a  nginx + tomcat5  website ,

server based on 
system : redhat linux  
cpu*8 :     ( Intel(R) Xeon(R) CPU   E5310  @ 1.60GHz )
mem  :  8G

 I don't know how to use these parameters well . and what else should I add ? maybe I added something  excess  ?
can I find some books to learn about all the parameters and the numerical value ?
