iPad Big delay while delete a word in safari (google)

[prymitywista]

Hi!
I've got problem: when I want to delete a word from searchfield in google then I've got 1-2sec lags but only when I'm trying delete letters in search field inside website, not in safari itself (not in adressbar).

Anyone has got something like this too? Or can now what's going on...?

iOS 8.1, iPad Mini Retina
