Well. PHP 7 has a completely reworked opcode cache and many other tweaks that increase its performance across pretty much all applications tested (including the Zend framework itself according to Zend). With that said, however, as we mentioned earlier, we will not shy away from the comparison. We are working towards a performance benchmark that will compare Peachpie and PHP 7. But as we haven't focused on performance optimization yet at all, we don't expect Peachpie to outdo PHP 7 quite yet. Give us a few days/weeks and we'll publish the first benchmarks. We're curious as well :)
