On the demo page in Chrome, Faster.js is actually slower.

For me faster.js was faster for 2 seconds then it became slower and slower in Firefox

faster.js was about 9ms faster on my mobile device.

For me faster.js seems to be slower in Safari about 2-3ms.

it works out to 20-25% for me, but I'm on 10.13.5 beta, not sure what changes have been made in safari.
