The other day, a friend mentioned a latency number to me, and I realized that it was an order of magnitude smaller than what I had memorized from Jeff’s talk. The problem, of course, is that hardware performance increases exponentially! After some digging, I actually found that the numbers Jeff quotes are over a decade old .
Without further ado, here it is.
 Jeff’s numbers are from 2001, and were first publicized by Peter Norvig in this article.

 The hardware trends I’ve gathered are rough estimates. If you want to tweak the parameters yourself, I’ve made it really easy to do so – please send me updates! Better yet, issue a pull request.
