Speed is the least significant reason to change keyboard layouts. You can get to 100 wpm typing with two fingers, evidenced on YouTube. Layout doesn't matter if you want to type fast. The main reason is comfort, which is harder to demonstrate but very obvious in my experience (as someone who switched to Dvorak 11 years ago but still regularly uses qwerty at libraries).
