So, let's talk about SQL performance tuning. This is just a fancy way of saying, ‘Let’s talk about making your database queries run faster’. You are probably already aware that slow queries can make your applications sluggish, frustrate users and even stall business continuity. So, how do you tune your SQL Server for better performance? Well, there are many ways to go about this, but in this post, we explain four of the simplest ways to secure speed for your SQL queries.

1. Indexes and Maintenance: Think of Indexes in SQL Server as the table of contents in your book. They help the database find the data it needs quickly without having to search through every single page. In other words, they are like a shortcut to the data being queried from your database. Sounds like a good thing to have, right? We confirm! Adding indexes to your database tables makes for faster searches and of course, better query performance. Once indexes are added, proper maintenance makes sure your results are consistent. As a final step, we encourage you to create a maintenance job to support you with periodic index maintenance.
2. Table Partitioning: This simply means dividing large tables into smaller chunks, called partitions. Partitioning enables your SQL server database to only search for relevant parts of a table instead of the entire table every time a query is launched. It is like dividing a big task into smaller, more manageable ones. As you can already tell, this will help your SQL queries run faster.
3. Use Materialized Views to store the results of complex queries: This way, your database does not have to run the same query every time these results are required. It is like having a cheat sheet handy for your SQL Server. This is most helpful for recurrent resource-intensive queries that return multiple rows of data.
4. Regularly Update Statistics: In SQL Server, up-to-date statistics enable the query optimizer to make accurate decisions on the best plan to execute any given query. It is, therefore, necessary to update statistics on tables and indexes in a timely manner so that the query optimizer can make correct decisions as to the optimal execution plan for a query. Outdated statistics can lead to inaccurate query plans, which can, in turn, lead to inefficient queries. Therefore, it’s essential to ensure your statistics are up to date.
