Useful Techniques to Improve SQL Query Performance

SQL performance tuning involves the recognition and implementation of error resolving techniques for enhancing application performance. Sometimes, the size of business databases makes it hard to find inaccurate segments and formulate a solution that suits the organization’s needs. 

 

Having worked with some of the best enterprises over the years, our experts at Tosska have ascertained some essential approaches that DBAs can utilize to improve SQL query performance. These strategies include:

 

1. Log Handling

 

If there’s one strategy that most DBAs tend to ignore, it’s log handling. A huge number of logs are generated on a daily basis in an enterprise application. Due to this, logs have become one of the major hindrances in the application. Here are some log handling strategies to implement:

 

• Transaction Logs – These logs require a lot of free space. Not having enough space kickstarts the grow file operation. This operation is costly, tedious and can obstruct the DML commands of the database.
  
  
  
  
• Virtual Log Files – Most of the applications have a higher number of VLF files that are essential in a transaction log. It is important to set the correct size so that the number of these files does not cause performance hits.
  
  
  
  
• Keep Essential Data Files on Separate Disks-  It is crucial to ensure that the server is not overloaded. In order to attain performance stability, you need to keep data files separate from the log files. Doing this from the start boosts performance.

 

2. Hardware Upgrading

 

Adding capacity and memory to your server is also an effective way to speed things up. If you don’t mind spending some money, then you must consider upgrading to robust drives. Aside from this, you need to make sure that you keep all the logs, data files and database backups on a separate drive. 

 

3. SQL Queries

 

As experts, we have observed that most performance issues arise due to badly written queries and poor query plans. These issues generally occur from a lack of experience in managing large scale enterprise databases.

 

Tuning the response time of a query is highly important. In fact, there are several optimizing tools that you can use in order to improve SQL query performance. You may connect with Tosska Technologies if you wish to purchase a tool that offers the ultimate SQL performance solution in just a few clicks. 

 

4. Handling of Indexes

 

Indexing is usually neglected during the development procedure, but if you have a great indexing strategy, you can improve SQL performance quickly. Indexes are information structures that enable you to choose and sort the columns in a database table. They enable quicker data recovery by giving simple access to systematic records. Although setting up indexes doesn't require a lot of coding, it does take a bit of thought.
