   There is a LOT of magic secret sauce that Google uses to do that.   
   Sorry, I'm not at liberty to describe any of it.  Suffice it to say that   
   conceptually, Google does some things that you would probably recognize,   
   but considerably differently.   
      
   I'd suggest that you use Google Chorme's (et al.) "Developer Tools" (or   
   anything else that provides similar visibility into page load) and look   
   at the various things that happen when using Google search.  At least   
   that will give some visibility into what you can see from a client.   
      
   You might want to search for the phrase "Google Global Cache".  Google   
   does publish some information.  I know that there have been some   
   articles from outside of Google that speculate on things.  Suffice it to   
   say that Google search uses more magic secret sauce than GGC does.
