As per my understanding upstream\_response\_time is subset of  
request\_time.

# request\_time : This shows how long Nginx dealt with the request

# upstream\_response\_time: Gives us the time it took our upstream server

(in this case Apache/mod\_wsgi) to respond

request\_time = time nginx got the request to the time it sends the  
reponse to client(browser).

request\_time = variable component + upstream\_response\_time

Can anybody explain me what exactly the “variable component” is ?
