How Does Performance Testing Directly Impact Your Business

When you are unable to handle an unusual amount of orders during the holiday season, for example, your web application performance has a direct impact on your online business. Performance, particularly perceived load time, is very important for a positive user experience. A page that takes longer than 3 seconds to load will be abandoned by 53% of users, and a one-second delay may cost online retailers millions of dollars each year in sales. The average cost of a network outage, according to Gartner, is $5,600 per minute. The worst-case scenario is that your website goes down on Black Friday.

Unfortunately, if you are not prepared to manage an increasing number of concurrent users, this may occur. Ecommerce companies spend a lot of money on advertising, yet the increased traffic that marketing brings might catch them off a surprise. Web application performance testing, particularly load testing, should be done on a regular basis to avoid performance concerns and provide consistent, optimal performance under a variety of scenarios.

Entrepreneurs don’t need to know how to load a website in detail, but a fundamental awareness of operations that are critical to your business and for which you pay is beneficial. This article will teach you what performance testing is, when it is done, and how it is done. For this purpose, hiring a professional company that provides performance testing services is a good idea.

Best Practices in Performance Testing

Load testing should be done on a frequent basis to provide the optimal user experience. There are a few ‘best periods’ to measure web application performance:

  • When the product is virtually finished (all important features have been included);
  • Once the application has reached a state of functional stability;
  • Following a code update or the setup of new hardware or software;
  • Individual product units or modules (e.g., to evaluate the pace of interaction between microservices);
  • When the website has grown by a certain level;
  • Before events when you predict an increase in the number of web visitors;
  • Following a low-scoring consumer sentiment survey or a poor user satisfaction test;
  • If you’ve observed that the site is struggling in ways it hasn’t before.

Load testing is performed by many firms that use the Waterfall process after the software development process or whenever a new version is published. Load testing web applications should be done on a regular basis by agile teams. Stress testing should be conducted on a regular basis, particularly before important events such as Black Friday, ticket sales for a big show, or elections. This will guarantee that you are aware of the system’s endurance capabilities and that you are prepared to deal with any unexpected traffic spikes or performance difficulties that may arise.

Mission-critical applications, such as space launch projects or life-saving medical equipment, should be thoroughly tested to guarantee that they perform as expected over an extended period of time.

1. Determine the testing environment as well as the tools that will be used

Software, hardware, and networks are all set up in a testing environment to run performance tests. Early on, developers must determine the physical test and production environments, as well as the tools available and any performance testing problems.

One of the performance testing best practices is to test in the actual production system or a duplicate of it. If a live site is being tested, many companies prefer to do it outside of peak hours to avoid causing problems for real users. If performance testing in the identical production environment is not practicable, a subset of the production system with fewer servers of the same or lower specification may be used instead. At the very least, the team should endeavor to match the hardware components, operating system and settings, network, databases, software requirements, and other programs that are utilized on the production system.

It’s critical to imitate production settings as much as possible for load and stress testing in order to get an accurate picture of web performance. Occasionally, this entails bombarding the app with millions of requests. Most firms currently use load testing tools or services instead of doing it manually. The protocols supported, licensing cost, system requirements, and platform support all influence which tools are used for testing.

2. Establish objectives and performance acceptability criteria

We carefully discuss the customer’s requirements and business needs before doing performance testing. It’s critical to establish whether the system meets the demands of the clients. We also do system analysis and generate a preliminary list of suggestions for load testing and instances that might overwhelm the system, such as picture uploads, file production, or delivering significant volumes of data.

The QA team should test the most common flows for your users and determine which metrics are most important to them as well as the web app’s performance in the browser and on the server.

3. Create and plan performance evaluations

A clear testing plan must be developed by the team. A variety of end-users must be simulated, performance test data must be planned, and metrics must be defined. The testers create important scenarios to test for all use cases as well as certain specific scenarios that the app is likely to encounter. They need to know what those people were doing to determine why performance decreases at a certain number of users. Different user trips should also be represented according to the quantity of those travels in different periods during the test, representing probable traffic peaks.

4. Set up your testing environment

The team sets up the testing tools and creates a specialized testing environment that closely resembles real-world settings, as well as automating deployment to that environment. If an online store, for example, receives a large number of overseas visitors, it requires a corresponding infrastructure as well as load testing scripts that include tasks done by virtual users. Then they must automate the start of the performance tests as well as the recording of the outcomes.

5. Put the test plan into action

The performance tests are created by the team in accordance with the test design. They set up the scenario setting and schedule before executing it. A huge amount of unique data should be available in the data pool, and the number of users for each scenario or script should be determined.

6. Carry out the tests

The team runs and supervises the tests, as well as collecting the results. The run-time transaction, system resource, Web resource, network latency, and other monitors may all be used to examine a situation. At least two rounds of testing are routinely conducted by teams. The first round provides an opportunity to detect any potential issues.

The team then repeats the tests, either with the same settings under the same conditions to establish consistency or with alternative settings to see what happens. The team may require further testing iterations based on the results.

7. Perform an analysis, fine-tune, and retest

The team may assess the test findings using graphs and reports created during scenario execution once the web app’s performance has been measured with data. They may now discuss their results and go to work on fixing any difficulties that have arisen. They fine-tune the software and then perform the tests using the same and other parameters to see how much better it is.


For an online business, a software’s continuous level of performance has several advantages. Performance should be viewed as a critical element of a software product, and testing should be a continuous process that is integrated into the entire strategy.

The majority of performance difficulties are related to speed. Testing the performance of a website or application helps you to enhance it and its overall performance, resulting in a better user experience, lower bounce rates, more conversions, more customer satisfaction, and more sales and income. You can be aware of any prospective difficulties and prepare how to deal with them in advance by using various sorts of performance testing. Hiring a professional company that provides performance testing services is a good idea in this case.
