If you would like to use Raptor to start performance testing your apps to get these numbers down, it's all documented on MDN [1]. These numbers were captured on a Flame-KK with 319MB of memory with the light reference workload, which is the baseline device for v2.2 -> v2.5. Raptor does require Node v0.12 [2], so if you find you need to switch between Node 0.10 and 0.12 for Gaia, I recommend something like "n" [3] to easily switch between.
