You guys are forgetting about google fiber. Its router is a dual core MIPS with hardware acceleration capable of supporting the config that google uses. Essentially ISP hardware provides most of the performance of gigabit internet speeds. It doesnt matter how optimised the code is, whats important is that the hardware is also capable.
The Google ONT/RG's are pretty smart - perhaps a bit too smart, as all subscribers are part of a big data experiment - there's an incredible amount of stuff inside them, think NVF/SDN stuff - so they can update and manage them on the fly with various services, etc... was fun looking into them on a recent visit to the SLC area where Google Fiber is present (and the home where I was staying had google fiber).
There is a reason why I do not have OnHub's, Chromebook's, or Android's on my primary LAN...
