I’m managing a high-traffic web application and noticing performance bottlenecks in our SQL Server database. What are some best practices for optimizing SQL queries, indexing strategies, and overall database performance? Any tools or techniques for monitoring and improving performance would be greatly appreciated.

I’ve tried optimizing SQL queries, adding indexes, and analyzing query execution plans. I’ve also used monitoring tools like SQL Server Profiler and Performance Monitor to identify bottlenecks.

I’m looking for advanced optimization techniques and best practices from experienced developers to improve overall database performance and handle high traffic more efficiently.
