Liftoff is still substantially slower at initial compilation than Firefox. Are there any plans to close the gap? A Unity exported game takes over 40 seconds for a new model low end Chromebook to compile. The upcoming 3 fold decrease will be nice, but FF could do it in 2 seconds on the same hardware.
