Just to make it perfectly clear to Sengadog and Virtualgeo -
I can confirm that both momolorient and les are correct - Safari under iOS 8.0.0, 8.0.1, 8.0.2 AND 8.1 is cripplingly slow when compared to Safari under iOS 7.x
A side by side test comparison between two iPad (3rd gen) Wi-Fi + Cellular illustrates it as self evident that there are a genuine issues here, along with delayed keyboard response and links that play dead!!
FYI - I'm wholly disinterested in being advised to "reset this, reset that, restore this, restore that" because none of that hocus-pocus works any better than crossing your fingers and spitting into the wind!
How can Apple take an application that worked just fine under iOS 7.x and "upgrade" it so that it's barely usable!
Any connected device that falters on the most crucial of functions is analogous to having the newest car on the block only to have it keep stalling every 10 yards (metres)!
Apple need to focus on getting the engine running properly and not on spurious functions like Continuity, iCloud Photo Library, Apple Pay etc. - which the majority of users never even bother with!
I was no fan, but Steve Jobs' legacy is just being p!$$3d up the wall!
