Okay I forced closed just about everything and I did a quick scroll of this forum and using the Safari browser is definitely smoother than the Atomic browser. The difference isn't much but when you roll the page down with Safari it just continues to move with no hesitation but with Atomic there is a slight hesitation. I tried on wifi and 4g with no difference. The wifi has a 2 download and the 4g( Seattle) has a 25 download. Safari is just smoother but I do like the tab arrangement with Atomic
