Benchmarks at this point would be pointless, Servo doesn't do so many thing Gecko does that any benchmarks is pointless.

E.g. Gecko renders every element on the page according to spec and spends 10seconds, while Servo renders like two in a millisecond (because it stubs the others).

To make stuff worse, Gecko will be super-optimized for browser benchmarks (like storing previous values of used functions to speed things like sin(x) ) that Servo will look way slower than Gecko, or maybe even Firefox 6.
