Database Performance Tuning: Indexes, Partitions, and Caching Tuning database performance means making careful, small changes and watching their effect. Start with a clear goal: faster queries, steadier response times, or lower load on the database server. Then use measurement before and after each change. This article focuses on three powerful tools: indexes, partitions, and caching. Indexes Indexes speed up data access, but they also add write cost. Use them where queries are common and selective. ...

SQL Query Optimization for Performance Performance starts with understanding the data and the workload. Start by collecting representative questions your app runs most often. With this insight, you can balance storage, indexing, and SQL writing. Small, deliberate changes often add up to big gains. Focus on indexes first. Create indexes on columns used in WHERE and JOIN clauses, especially when the column is selective. A covering index (one that has all the columns needed by the query) can avoid extra lookups. Be careful not to over-index; too many indexes slow writes and take space. For example, CREATE INDEX idx_orders_date_status ON orders (order_date, status) helps date-range and status filters. ...
