It's exponential, but by a factor of 2 - not 3 
Twice as fast yields 4x the resistance. Assuming the same distance traveled -- doubling velocity will require 4x the power to move a given mass  But you're point is still valid (but finding the actual speed where it's not effective seems like a good exercise - I would hypothesize that it's faster than an intuitive guess).
