Aren't micro-benchmarks kind of pointless if they don't reflect real-world behavior? The fact is that javascript execution (not networking behavior but javascript performance) on many web apps differs by orders of magnitude between Firefox and Chrome. There are a handful of sites that I find literally unusable in Firefox on a new Macbook Pro because even after loading, sitting in the background doing nothing, they make the entire computer unresponsive due to high CPU usage. These same sites work just fine in Chrome and Safari.
