Practical Tips for SQL Performance Tuning

Software teams that are reliant on relational databases require expertise in SQL performance tuning. It doesn’t just have to be vital for us to call it that. Unfortunately, rare is another option.

RDBMS settings can be left as they come by default by many software professionals. That’s incorrect. Your RDBMS comes with default settings that aren’t always optimal. Performance issues can easily be avoided if such settings are optimized.

In contrast, some programmers think that even though SQL performance tuning is important, only DBAs should handle it. That’s also incorrect.

The first thing to note is that not every company has a designated DBA. It has to do more with the size of the company than anything else.

Although there may be a dedicated DBA on the team, that doesn’t mean they should be given tasks the developers themselves could’ve performed. Developing a slow query shouldn’t be a problem if a developer can diagnose and fix it. In most cases, they can’t – the relevant word is can’t.

What can we do to fix this problem?

By providing developers with the knowledge they need to find slow SQL queries and perform performance tuning, we enable them to do better SQL Server performance tuning. I’m going to give you seven tips on how to make that happen.

The purpose of Tune SQL is to improve performance.

I figured we should define SQL performance tuning before we list our tips you can use to do it on your software organization.

How does SQL performance tuning work? Even if it’s a vague idea, there’s a good chance you have one.

The purpose of SQL performance tuning is to make queries of relational databases as fast as possible.

There is no single tool or technique that can improve SQL performance, as you’ll see in this post. It is a set of practices that utilize a variety of tools, techniques, and processes.

Methods for finding slow SQL queries

Here are seven methods you can use in SQL Server to find slow SQL queries.

As an example: Create a detailed execution plan

SQL Server Management Studio makes it easy to create graphical execution plans, which you can use to diagnose slow queries. When your queries are run, an execution plan is generated. How are execution plans generated?

Using SQL Server Management Studio, click on “Database Engine Query”. Enter the query and click “Include Actual Execution Plan” on the Query menu.Click “Run Query” to run the query.¬†Alternatively, you can click or press F5 to execute the command. In the results pane, on the “Execution Pane” tab, SQL Server Management Studio displays the execution plan.

Monitor the use of resources

When it comes to SQL database performance, resource usage is a crucial component. You can’t improve what you don’t measure, so monitoring resource usage is definitely necessary.

What are your options?

You can measure the performance of SQL Server using Microsoft’s System Monitor tool. SQL Server objects, performance counters, and other objects’ behavior can be viewed.

When you use System Monitor, you can simultaneously monitor Windows and SQL Server counters to determine whether there is any correlation between the two.
