1. Check the execution plan. Is it using the right index? Is it missing an index that I think can help? 2. Look at the WHERE clause. Is it filtering efficiently? 3. Review Joins. Is it joining more tables than it needs? 4. Reduce the result set early. Can I limit the rows before doing heavy calculations?
Improving performance is rarely about rewriting the whole query. Most of the time you can improve it with one or two tweaks.

When a query is slow, here’s my usual process:
1. Check the execution plan. Is it using the right index? Is it missing an index that I think can help?
2. Look at the WHERE clause. Is it filtering efficiently?
3. Review Joins. Is it joining more tables than it needs?
4. Reduce the result set early. Can I limit the rows before doing heavy calculations?
Improving performance is rarely about rewriting the whole query. Most of the time you can improve it with one or two tweaks.
