Optimizing MariaDB for maximum performance
The document outlines various strategies for optimizing MariaDB performance, highlighting the importance of examining system settings, server variables, and storage engines. It suggests specific configurations for memory allocation, connection handling, and buffers, as well as considerations for different storage engines like InnoDB and MyRocks. Additionally, it provides insights into best practices for query design and management for optimal performance.
