For my tests, I used the same computer and the same DB files. The procedure was install and uninstall MariaDB and MySQL to have a comparable system. You can check the complexity of the queries and the database schema if you download the source code of my application (search directly the XML files that contain all db schema and queries used by the application). If you want more information about the queries, I can send you a database and a report with the queries, the benchmarks of the MariaDB and the benchmarks of the MySQL. I collected this information when I contacted with Monty to explain my results of the test and congratulate by their improvements.
