ELI5: How come new e-mail is first pushed to my iPhone before I can see it on mail.google.com?

I noticed when an e-mail arrives to me, I get a notification on an iPhone. When I try to read it on desktop, I have to wait few seconds (even after refreshing) before it appears in GMail web interface. How can the e-mail be pushed faster? Or is GMail web interface so slow?

The gmail web interface is a "pull" technology -- the page periodically refreshes itself and checks for new mail. If your mail is being pushed to your phone, then it will get it very quickly, while your gmail session is waiting until it checks mail again.
