Though I don’t have specific numbers to share, WebKit2’s design generally provides much better performance under these conditions:

(1) Faster: Long-running JavaScript programs on iOS;

(2) Faster and smoother: Scrolling;

(3) Faster and smoother: More than one webpage open at once;

(4) Less memory use: opening and closing many webpages over time.
