I have a Mac and I'm on Verizon fiber optic into an Apple Airport WiFi. The display is pretty much instantaneous. I think the ads are pretty, and I've never seen any pop-ups.

BTW, scroll down on the main page and there's an entire Forum section devoted to user questions. You should post your question there. And maybe do a search for other, similar comments. This issue arises from time to time and appears to be totally related to individual users setups.
