Database Performance Tuning Checklist
Index Optimization
Analyze query execution plans to identify missing indexes.
Ensure that indexes are used effectively by reviewing index usage reports.
Remove or consolidate duplicate and unused indexes.
Consider index fragmentation and rebuild or reorganize as necessary.
Evaluate the need for composite indexes based on query patterns.
Query Performance
Review and optimize SQL queries to reduce execution time.
Use query profiling tools to identify slow-running queries.
Avoid using SELECT * and specify only necessary columns.
Implement query caching where appropriate.
Ensure that queries are properly parameterized to enhance performance.
Resource Management
Monitor CPU, memory, and disk I/O usage for the database server.
Configure appropriate memory settings for the database instance.
Implement connection pooling to manage and reuse database connections efficiently.
Set up alerts and monitoring for resource bottlenecks.
Regularly review and adjust resource allocation based on usage patterns.
Database Configuration
Ensure that the database is using the optimal storage engine for your workload.
Review and tune database configuration parameters for performance.
Enable and configure appropriate logging for performance analysis.
Regularly update statistics to help the query optimizer.
Consider partitioning large tables to improve query performance.
Backup and Recovery
Regularly test backup and recovery procedures for efficiency.
Ensure that backups are taken during off-peak times to minimize impact.
Keep backups on separate storage to avoid data loss.
Automate backup processes to ensure consistency and reliability.
Monitor backup performance and troubleshoot any issues promptly.
