What is SQL performance tuning and database performance tuning?
SQL Server performance tuning encompasses a set of processes and procedures designed to optimize relational database queries, so they can run as efficiently as possible. SQL tuning involves several elements, including identifying which queries are experiencing slowdowns and optimizing them for maximum efficiency.

How can improve table performance in SQL Server?
- Add a single column index to each column.
- Add specific indexes for the most common queries so they are optimized.
- Add additional specific indexes as required by monitoring for poorly performing queries.
Which is better temp table or CTE?
If you are joining multiple tables with millions of rows of records in each, CTE will perform significantly worse than temporary tables. I’ve seen this from my own experience. CTE’s perform significantly slower. CTE’s also perform slower because the results are not cached.
How can I improve my CTE?
Four Ways to Increase CTE Enrollment Posted on
- Get more exposure to your program. Let’s start with perhaps the simplest fix: exposure to your CTE program.
- Make CTE classes more accessible to students.
- Focus on hands-on learning in your CTE classes.
- Offer incentives to career & technical education students.
