This chapter gave you an overview of the hardware that exists for MariaDB and which one is better than the others. You also now know how to take advantage of some hardware and operating systems for MariaDB. You've seen a quick overview of which MariaDB engines are available and which ones are faster. Selecting the correct hardware is a very important thing, and to know how it works is a completely different topic. Take time to understand how to optimize and how your environment works to avoid misunderstood slowdowns. As a rule, try to keep yourself updated on the new CPU features / power management and how Linux evolves with it.
