Has this actually been verified by _anybody_?
I'm sorry to say that I have not heard of a single performance improvement
on x86. I know, I know, it's been one of the touted features of 3.0.x, but
I've not actually seen code that actually _runs_ faster, only code that is
larger and slower.
Last I saw, spec numbers were lower too. Where are these much-told-about
improvements exactly?
