According to this presentation about WebGL2, this feature (available for WebGL 1.0 as extension) can lead to significant performance gains. Interesting bit:

Google Maps uses and requires instancing support — Reduces vertex buffer size by 6x (!)

The concept is:

To draw 1000 soldiers
1000 draw calls, with different position, posture, etc
Or, with instancing, only 1 draw call
Big perf improvement

cc @ansis @kkaefer @jfirebaugh @lucaswoj what do you think? Can we use it?
