Well, the goal of this post is to present a potential approach. (Of course you can take a peek at the "So What?" section)

Responsive Sites Are Optimized
Danny writes: The user does not get a fully-optimized experience for the device they are using.
Hate to hammer in the previous point, but that's where specific media queries are great. They allow us to make changes in the mark up to hide elements on smaller devices with different classes.

Not all of this is due to C being faster than Erlang. A good chunk of the performance boost is just being able to embed the persistence engine in-process. That alone cut out a lot of CPU and overhead by avoiding transmitting data across processes and converting to Erlang in-memory structures. …
