Well, whenever you're seeing a higher than expected CPU usage on your system -- your first action is to run "perf top -z" as root => this will directly show you what is hot on your system right now (regardless if it's MySQL related or something else), and you will know *what* is hot. And if it's MySQL Server, then you'll also see in which functions you're eating most of your CPU time (and then you can run the same on your 5.7 servers and compare).
