Yep, which is what I meant in my comment you're replying to (as per my statement that devtools only report to the 0.001). But as pointed out by jclem, I'm probably wrong about microsecond response times anyway. I'm very likely thinking about the MICROseconds I see in dev, which of course doesn't count :) But with the heroku link above, I am seeing as low as 1-3 MILLIseconds in Toronto, Canada.
