Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Measurements refer to specific data points, such as the number of seconds it takes to process a request. Memory utilization: The amount of memory required to process a request.

long_query_time: Defines the threshold for query execution time, and queries taking longer than this threshold are considered slow and logged for further analysis innodb_buffer_pool_size: Sets the size of the InnoDB buffer pool. This KPI is also directly related to Query Performance and helps improve it.

Failover mechanisms The primary purpose of failover — the automatic process of switching from a failed or offline database server to a standby or backup server — is to ensure user access and functionality of databases without interruption, even if there is a hardware or software failure.

A finely tuned database processes queries more efficiently, leading to swifter results. Inefficient query design, such as utilizing SELECT * instead of specifying necessary columns, can escalate data transfer and processing overhead. Query plan analysis can also provide valuable insights.

Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

Micro-optimizations are great for keeping performance on track, but it’s critical to have clearly defined targets in mind — measurable goals that would influence any decisions made throughout the process. Also, as Patrick Meenan suggested, it’s worth to plan out a loading sequence and trade-offs during the design process.
