What are the most effective ways to test database performance?
Establishing performance goals for a given database system should not be solely reliant on quantitative aspects, such as KPIs; qualitative factors should also play a significant role in defining these objectives. To provide optimal recommendations for performance tuning, DBAs must possess a thorough understanding of the load patterns generated within the database by the application layer. This depth of knowledge enables them to effectively advise engineering teams on the appropriate utilization of database resources, avoiding common pitfalls like batch processing, over- and under-indexing, over-fetching etc. Therefore, it's crucial to maintain a continuous proactive monitoring to be effective in further performance tuning.
