I read it as - the browser is fast at its core but still needs to optimize for the advanced HTML5 features. I guess it will get better over time. This is a good start. No matter what people think, this is a great step forward. Web as a platform is only as open as the variety of rendering engines providing standards compliant features are. If all the browsers are standardizing on the same rendering engine, it's not the web platform that is standard but that particular rendering engine. Even if it is open source, having multiple competing implementations supporting the same standard is a good thing. Especially when companies would like to push for features that benefit them at the expense of overall community.
