How do you improve the DB Performance?

Question

Accepted Answer

To improve DB performance, optimize queries, use indexes, increase server resources, and implement caching.

Optimize queries by using proper indexing and avoiding unnecessary joins
Increase server resources like CPU, memory, and storage to handle larger workloads
Implement caching mechanisms to store frequently accessed data in memory for faster retrieval
Regularly monitor and tune the database for optimal performance
Consider partitioning large tables to distribute data and improve query performance

Accepted Answer

A. Look into the execution plan and find if some Table Scan, Cluster Index Scan, key lookups are present. If yes, try to overcome these by changing the query structure or index structure. Also, check for the index fragmentation and if more than 30%, rebuild the indexes and update stats.
