If you happen across a new speed comparison between IE9 Final Release and Opera 10.6x or 10.7xBeta please post it on FR. Only comparisons I’ve found were with a release candidate for IE9 from early August.
I’ll do the same if I find one posted online.
Would you ping me when/if you find that comparison? I just updated my Opera to 10.62 last night. So far it's blazing fast! Even FR is loading faster. If IE9 can beat it I'd be surprised.
