OK, after reading this article I've kinda snapped it, and did some browser testing myself. REAL testing, not something like "we'll choose these few java scripts and test only them"..
So a friend and me sat on the same computers, inside same LAN, and he tried out latest non-beta Opera, Chrome and FF, and I was playing with my beloved Maxthon2+IE8 RC1.
So in the end, if we compare the setup which I always use (activex/flash/scripts ENABLED, but Ad-blocker ENABLED) and setup he always uses (everything disabled+FF ad-blocker) I'm still somewhat in front of him with IE8+Maxthon2. But it's not huge difference, as I doubt many people open 100 pages AT ONCE. And on the sample of 10 pages, he'd have them opened in let's say 8 seconds, and me in 6. Does it matter much? Nope. Because some other 10 pages I'll be loading in 15 seconds, and he'll load them in 10. But we won't die because of those few seconds, or <1s per page.
Oh, and I'v mentioned Opera and Chrome in the start. Opera was more or less the same as FF, and Chrome was slow as hell, cos it was opening 5 pages at a time, and paused between them a bit. So it took a while.
I'd say there was certainly no loosers there, not in speed. And certainly not a 6:1 ratio.
And we tested REAL websites, in REAL user scenario. No benchmarks, just pure browser power.
Well, enough of my rants, there won't be much point anyway, as I doubt either FutureMark, Microsoft or FF Foundation will listen to this :/
