> In 15 years, we'd get 10 doublings, which would make modern computers 1000x faster. Our original Toy Story frames were averaging four hours, which is 240 minutes, so we might naively expect that we could render frames in just 15 seconds. We didn't really achieve that: our average render times were probably on the order of 2-4 minutes per frame (the original productions weren't instrumented to keep accurate statistics on rendertime, and we never bothered to really reinstrument them to do so.) The renders were fast enough that most of Toy Story was rerendered in "render farm white space", we never had any sizeable backlog of work queued on the farm.
