The fastest way to boil water is to have high-power stove (Pocket Rocket, Giga Power) and heat exchanger pot- like a Primus. There is a video of such on YouTube. However, my curiosity if whether, if left on too long, or more dangerously, boiled dry, the high heat might warp the fins on the heat exchanger. Heck, boil any alum pot dry and you should expect problems. (thus the rumored safety shut-off valve in MSR's Reactor. "When you play with fire, don't be negligent"
