It is odd. Web sites load noticeably faster, but web _apps_ take longer to load than Chrome. Only tested on Google SPAs so far, though, so it may be a lack of optimization.
That is easily explained by faster rendering / CSS (Stylo) but a slower JS engine (vs V8)
Google sites load faster in Google Chrome. It makes sense.
Hmm, Google Docs and Gmail are fine for me. Are you using any extensions?
