Yep, I need to still learn how to install MySQL Tuner, guru Ken! 😀
What my commenting shows is that I had to dig around quite a bit to determine what needed to go into this my.cnf file.
Actually, the way that I experimented was to make some changes and then run that "perspective.php" file. I am sure that MySQL Tuner would be better. I really haven't touched this my.cnf file for a few years.
