> half a billion queries a month across 14 tiny VPSes

For reference:

  $ units -1v '1|2 billion reqs/month / 14 servers' 'req/sec/server'
        1|2 billion reqs/month / 14 servers = 13.580899 req/sec/server
I always do this when I see large-sounding query counts; a month has a lot of seconds in it, and it’s easier to visualize only one at a time: I can imagine hooking a speaker up to the server and getting a 14Hz buzz, or do a quick mental arithmetic and conclude that we have ~70ms to serve each request. (Though peak RPS is usually more relevant when calculating perf numbers; traffic tends to be lumpy so we need overhead to spare at all other times which makes the average much less impressive-sounding.)
