Safari 6.1 Laggy

I just updated to Safari 6.1 and i am not happy about it, its laggy on several sites and i cant upload pictures on facebook, when clicking upload picture it seem to freeze so i have to force quit the whole Safari, and when it comes to the lag.. when i open a page and it seems to be loaded i scroll down and nothing happens untill maybe 1-2 seconds later and still while scrolling its lagging.. i am nto happy with this.. is there a solution ?
