I'm just curious. Is this due to huge page change?
No, it's from enabling "DFA pass by default" in the optimizer:

I was going to make a comment when I saw these results also. It helped the
synthetic stuff a LOT, and more than corrected the mandelbrot regression
(since 7.0), but not "real apps." Still nice to see for comparing with
HHVM. :-) And of course it helps isolated areas of different apps, and more
optimizations will be added...
The "huge page" change you're referring to is Rasmus disabling them by
default now? If Intel doesn't enable them again, it should show *reduced*
performance on Wordpress, etc. (1% or more? Can't remember.)
Thanks.
