Build Variation and Benchmark

[Aftershocker]

Hi Guys,

I know there can be a large variation between the speed of the various buildbot builds. Has anyone come up with a reliable (or quick and dirty) way of testing them?  Can we use the original Wind Waker benchmark?  I'm currently using build  7636 just because that's the one I've stumbled on that works well for me on the Sheild TV, but having seen some Youtube clips I'm guessing there are faster still builds out there.
