What is database performance? There are two main aspects of database performance: response time and throughput . Response time is the total time it takes to process a single query and returns result to the user. It's critical metrics because it directly impacts the user's experience, especially in applications where fast access to data is essential. The response time includes CPU time (complex queries will require more computational power and increase processing time), disk access, lock waits in multiple-user environment (more about database transaction ), network traffic. Throughput refers to how many translations the system can handle per second (TPS). A transaction could include different activities to retrieve and manipulate data. A single command like SELECT, INSERT, UPDATE, DELETE or a series of commands could be used to trigger these activities.
