It flies, holy **** what an improvement! I swear, this is so fast it makes my head spin. I had 80 tabs open, not a single slow down. Memory stays around 230 Mb (Real memory), which is really impressive. It flies, no slowdowns what so ever. Pages are displayed faster, pages just in general feel more snappy. This makes any other browser look like child play. 80 tabs, and it makes no difference in memory used, and especially speed it makes no difference. It is like a whole new Safari, as if it was redesigned from the ground up. Wow, I am amazed.
