I am working on to figure out the performance bottleneck of a website. I am using the chrome empty cache and hard reload option and hitting it using the incognito mode(with no extension enabled).
For determining the page load time, using the network tab of chrome tools and it reports huge variation when i hit same page using the same(empty cache and hard reload) option.
For ex:-
Below is the first hit, which shows load time is 8.2 sec with 25 requests and 477KB data :-
Just after when i again hit(2nd hit), i get the same no of request and size but load time increases to 9.25 sec.
And in 3rd hit , it reduces to just 6.89 second.
Now, my question is that i am doing the same thing, then why the load time varies a lot.
