Great tutorial! PHP-FPM optimization is an important subject if you use PHP-FPM with Nginx or another web server to run PHP scripts and software. So often issues experienced with sites are related to PHP and SQL scripts taking long time or hitting limitations. Using this guide can at least fix a part of the issues .

The SQL query issue is a different thing though. The best would be to optimize the query in order to push down the query execution time as much as possible. This will increase performance. Sometimes if you use a custom database a redesign might help.

Good job!
