Introduction to MySQL performance optimization

What is performance optimization? In fact, we tend to define from a broad sense that the non-functional optimizations of a MySQL system will be considered performance optimizations, such as the stability of the database server, the number of SQL queries executed per second, the scalability of the system, CPU utilization, and so on, as the performance optimizations of MySQL.

I personally agree with this book that MySQL performance optimization should refer to MySQL Query response time optimization, MySQL performance optimization is to optimize the query response time to a customer or user experience to accept a degree.
