It sure looks like IE9 is optimising for some benchmarks.

Same could be said about firefox which only performs very good in its own benchmark ;)

Ya, I thought that was interesting too. You can basically tell which benchmarks are used as internal metrics by each dev team (which makes sense, since Google and Mozilla created their own benchmarks), but I wonder how much they look at performance in the others as well.

No need to wonder, in Mozilla's case:

Graphs are arranged such that lower is always better. The red line is current Firefox performance. Purple is Firefox's new in-development engine, called IonMonkey. Green is Chrome.
