The web is in just a shameful state. Even with 300 mbps fiber internet most websites are not snappy. As in, pages are so slow to render that I'll start reading, but then lose my place when the page reflows as it continues to load. Or click on the wrong thing because the page reflowed while I was trying to click on something.
As far as I can tell I'm actually CPU-limited, because I noticed no real difference from when I had 50 mbps internet. This is on a quad-core Macbook Pro that boosts up to 3.5 GHz...
