Netflix clocks 42B API requests per month (gigaom.com)

Interesting dogfooding here.

42B API requests / month = 42000000000 / ( 86400 * ( 365.24 / 12) ) => 15971 req/sec. From the graphs in the talk probably peaking to 30,000 req / sec.

Remember there are a billion nanoseconds going by every second.
