I know that bashing Heroku is popular this days but seriously i don't like what you did.

I'm not a fan of your way of getting users by pointing some non-objective figures and saying hey we're faster & better than the competition.

Seriously, you should benchmark and say "we can do this, this and this", and let your users decide if you're faster, better.. because doing it in your way, is just ugly and not fair.

Btw, I like your design. You mention redis on your site, but there is no redis in the pricing.
