Ubuntu 14.04 comes with MySQL 5.5.9 out of the box and I decided to give MariaDB a try after attending a talk by Michael “Monty” Widenius. He is the creator of MariaDB, and the original author & architect of the MySQL server. His talk was pretty inspirational for me. Anyway MariaDB is an enhanced, drop-in replacement for MySQL and yes, it even works with mysqldump. According to Monty, you should get a performance boost by just switching from MySQL 5.5 to MariaDB 10.0.
