how does HHVM compare to PHP 7 in terms of speed savings? PHP 7 is supposed to be pretty damn fast from what I have seen. I guess benchmarks are hard to read because they're dependent upon a lot of factors. It would be interesting to see two sites at similar scales running competing engines for PHP (hhvm vs. PHP 7).

Minor point of style: We tend to refer to phpng in lowercase, because that's the branch name. Although at this point, since it no longer exists as a branch (it's long since been merged into trunk) and there have been subsequent performance optimisations, the names "PHP 7" or "Zend Engine III" are possibly better.

Also, I partly responded to this above: https://news.ycombinator.com/item?id=8848129

TIL, thank you for that.

I have seen anywhere from 100% to 50% faster, with lower memory usage overall.
