How to Increase Database Performance – 6 Easy Tips

By Staff Contributor on May 10, 2021

Database administrators are all too familiar with the frustration of receiving an endless stream of calls about slow online performance. Instead of trying to resolve each individual issue as it arises, a better solution is to undertake database performance tuning activities that will improve online performance for all your end users. These activities can help you identify any bottlenecks in your system and ensure your infrastructure is able to handle increased loads.

There are several steps you can take to increase database performance. The following six easy tips can help you prevent or rectify possible issues with database performance. Even with these tips, it’s important to remember the best way to increase database performance is always by using the right tools. Based on my experiences and tests I can recommend SolarWinds® Database Performance Analyzer (DPA) and Database Performance Monitor (DPM).

By using even the free trial versions of these tools you’ll be able to:

  • Monitor and analyze the performance of database servers running individually, in clusters, and as cloud infrastructure.
  • Receive and implement database performance advice on specific databases and related queries.
  • Monitor database performance in real time and analyze past periods. In addition, the software tested by us enables the detection of anomalies in the load time and the location of bottlenecks in database performance.

After going through the best tips for manually improving performance, I’ll take a closer look at some of the best tools to help you improve performance even further.

Why Is Increasing Database Performance Important?

People often wonder whether it’s important to increase database performance. The truth is your business can only ever be as successful as your IT operations allow it to be. In fact, a high-functioning database can have a huge impact on corporate profitability. When data retrieval is slowed down by anything from a poorly written query to an indexing issue, a bottleneck that slows down performance and lowers productivity for the entire organization can emerge. When you learn how to increase database performance, you’re better able to avoid unnecessary financial loss as a result of server inefficiencies.

There are also many financial gains that come with improving the end-user experience. Since your customer-facing websites and applications retrieve data from your centralized database, inefficient indexes and suboptimal queries can have just as big an impact on customers as on your internal end users. As a result, your customer satisfaction is directly linked to database performance. That means knowing how to increase database performance can be one of the most important customer service tools in your toolbox.

Tips to Increase Database Performance

While there are many ways you can go about learning how to increase database performance, these six have proven to be some of the most effective and impactful when it comes to avoiding performance degradation.

Tip 1: Optimize Queries

In many cases database performance issues are caused by inefficient SQL queries. Optimizing your SQL queries is one of the best ways to increase database performance. When you try to do that manually, you’ll encounter several dilemmas around choosing how best to improve query efficiency. These include understanding whether to write a join or a subquery, whether to use EXISTS or IN, and more. When you know the best path forward, you can write queries that improve efficiency and thus database performance as a whole. That means fewer bottlenecks and fewer unhappy end users.

The best way to optimize queries is to use a database performance analysis solution that can guide your optimization efforts by directing you to the most inefficient queries and offering expert advice on how best to improve them.

Tip 2: Improve Indexes

In addition to queries, the other essential element of the database is the index. When done right, indexing can increase your database performance and help optimize the duration of your query execution. Indexing creates a data structure that helps keep all your data organized and makes it easier to locate information. Because it’s easier to find data, indexing increases the efficiency of data retrieval and speeds up the entire process, saving both you and the system time and effort.

Tip 3: Defragment Data

Data defragmentation is one of the best approaches to increasing database performance. Over time, with so much data constantly being written to and deleted from your database, your data can become fragmented. That fragmentation can slow down the data retrieval process as it interferes with a query’s ability to quickly locate the information it’s looking for. When you defragment data, you allow for relevant data to be grouped together and you erase index page issues. That means your I/O related operations will run faster.

Tip 4: Increase Memory

The efficiency of your database can suffer significantly when you don’t have enough memory available for the database to work correctly. Even if it seems like you have a lot of memory in total, you might not be meeting the demands of your database. A good way to figure out if you need more memory is to check how many page faults your system has. When the number of faults is high, it means your hosts are either running low on or completely out of available memory. Increasing your memory allocation will help boost efficiency and overall performance.

Tip 5: Strengthen CPU

A better CPU translates directly into a more efficient database. That’s why you should consider upgrading to a higher-class CPU unit if you’re experiencing issues with your database performance. The more powerful your CPU is, the less strain it’ll have when dealing with multiple requests and applications. When assessing your CPU, you should keep track of all the elements of CPU performance, including CPU ready times, which tell you about the times your system tried to use the CPU, but couldn’t because the resources were otherwise occupied.

Tip 6: Review Access

Once you know your database hardware is working well, you need to review your database access, including which applications are actually accessing your database. If one of your services or applications is suffering from poor database performance, it’s important not to jump to conclusions about which service or application is responsible for the issue. It’s possible a single client is experiencing the bad performance, but it’s also possible the database as a whole is having issues. Dig into who and what is accessing the database and if it’s only one service that’s having an issue, drill down into its metrics to try and find the root cause.

Elevating Database Performance With Tools

While these tips can help you increase database performance, manual efforts can only do so much. If you want to save time and energy while strengthening your performance optimization efforts, you should invest in a database performance analysis and monitoring solution. The following tools are the best ones on the market when it comes to increasing database performance.

1. SolarWinds Database Performance Analyzer (DPA)

SolarWinds DPA is a powerful multidimensional database performance solution that supports PostgreSQL, MySQL, IBM DB2, Amazon Aurora, SAP ASE, Oracle, Microsoft SQL Server, MariaDB, and Azure SQL databases. It focuses on bottleneck identification and offers automated index and query optimization advisors to help you target your database performance optimization efforts.

The solution uses response time analysis — which measures the actual amount of time it takes to complete an operation — to tune queries and improve overall database performance. DPA gives users the insights they need to align their resource provisioning with database performance to help ensure hardware isn’t interfering with performance.

Working in a database environment often requires database administrators or developers (DevOp) to observe the behavior of the entire environment in which their databases and applications run. DPA easily integrates the process of monitoring databases, hardware, and other entities used by applications and databases.

DPA can also be integrated with SolarWinds Storage Resource Monitor (SRM) to get a deeper understanding of your database performance. When DPA and SRM are integrated you can get contextually relevant information on the storage objects related to the databases being monitored by DPA. You can then correlate storage performance with the relevant databases.
