Mon Feb 04 07:47:31 PST speed versus throughput:

It occurred to me yesterday that while elevators have higher speed, escalators definitely have a higher throughput. In other words, if you were first in line, the elevator would get you to the ground faster -- but if you were last in line, the escalator would get you to the ground faster.

Imagine a 5 story building and you're on the top floor. There's one standard elevator that holds say, 15 people max and one standard escalator (running all the way to the ground floor). The escalator can hold at least 15 people at a time, probably way more.

You want to get to the ground floor. Assuming there are two even lines for each conveyance and people never change lines, which line would you rather be in?
