I believe this issue was known as “The Wall,” we hit it when working on Yahoo! Photos and had to throw away some objects to prevent IE from bogging down. (Firefox et al, naturally, didn’t show any problems here.)

To give an idea of what a performance hit this was, simple operations like looping through a collection of nodes were made incredibly slow after a large number of objects had been created.

I don’t know if “much faster” is necessarily accurate as I suspect a small number of sites may have been hitting this issue (plus it’s something that shouldn’t have been a problem to begin with) – “the new version doesn’t slow down” might be what I’d call it! ;) – but I am glad to hear they’ve been looking into it. (Memory leaks are the other biggie which I hear there’s been progess on as well.)
