Hello Clark, have you been able to find answers to your question about same/worse Percona performance in comparison to MySQL?
I’m trying to valuate the Percona, but my initial comparison of performance (using sysbench) between Percona 5.7 and MySQL 5.6
show the same results for both databases. I’ve applied the same my.cnf. The MySQL and Percona are running on separate boxes (same hardware), with the same Centos version. Used the following distro: Percona-Server-5.7.18-14-r2c06f4d-el6-x86_64-bundle.tar
