No surprises there. They're benchmarking their strengths: topsite
pageload, which is already somewhat optimized to be fast in IE and
doesn't include much scripting (compared to web apps), so their JS/DOM
slowness is not as apparent.
In other words they're saying they're fast on loading websites written
last year. We're aiming to be fast on websites written this year and
next year too. ;)

And here's a specific example:
It took both Chrome and Firefox 3.1 only 19 seconds to open and
start a 16-slide presentation in Google Docs, for instance, while
Internet Explorer 8 took almost twice as long at 33 seconds. It's
a sea change from IE7, but simply not enough to claim raw-performance
parity, and that's a problem that's only going to be accentuated when
Microsoft launches its own online apps with Office 14 next year. [1]
