I experience the same problem Selvan.
Maybe not exactly the same but...
I get the 3 second problem whenever I go to a website where the search bar of the site leads the page and I try to type something in the menubar search in the browser.
The problem is only with the menubar search in the aforementioned circumstance and only then.
I have just learned to live with it.
example of websites I have this problem with... Google mainpage, Cnet, and Accuweather.
