I think it's critical to examine the performance of Servo DOM+layout at its
most vulnerable, which I think is when JS is synchronously pounding on it.
A couple of microbenchmarks spring to mind:
1) DOM bindings performance for simple DOM operations, e.g.
for (var i = 0; i < 1000000; ++i) {
element.setAttribute("class", "foo");
}
2) Harder: performance of synchronous layout, e.g.
for (var i = 0; i < 100000; ++i) {
element.setAttribute("style", "width:" + i + "px");
element.getBoundingClientRect().width;
}
Showing Servo competitive on both of those would go a long way towards
validating the architecture IMHO.
Stuff like canvas, WebGL, floats etc is far less interesting to me. There's
no reason to believe they'd be hard to make performant in Servo.
