Did you experience these issues on 8.0 or just 8.1? I remember having issues with the forums going back to 7.1.2 so I'm curious if this is an eIC related problem. It was still usable back then but now I get more lockups and Safari freezing in 8. I think one thing is for certain, the upgrade to 8.1 made my Safari experience worse. I'm unsure if it is eIC or Apple.
