performance degradation, however it will not be that dramatic: when we
upgraded, we switched to HHVM from PHP 5.3 which was really outdated,
while 5.6 and 7 provided nice performance improvements.
In particular, I've heard good things about PHP 7 performance. Someone less
lazy than I am at 5pm might want to do some research on that though.
I can say that PHP 7 locally runs unit tests significantly faster than PHP
5.6, although that's not really a representative workload for running a
website.
