Thanks. I measured the 30% improvement in Firefox Aurora on Win XP pro and Win 7 by doing the following:

var _foo={time:0,frames:0};
function _paint(...)
{
_foo.time-=Date.now();

/* body of the _paint function */

_foo.time+=Date.now();
_foo.frames++;
}

Comparing the average time per frame of three implementations:
* A. mine,
* B. the one from oct 29 ( when you announced 40% improvement ),
* C. the latest one

There was an improvement of 40-45% b/w A and B and 30% b/w A and C.
