    Software testing techniques determine the quality of an application. There are various types of testing that are used to validate software. One of its types is Performance Testing.

    We are also offering performance testing services in India & USA, hence very well aware of it. Basically, this testing method is non-functional whose aim is to identify the performance of an application based on certain parameters like speed, scalability, stability & responsiveness.

    Performance testing is a must-to-do activity because it ensures a better user experience. So many times, we have experienced ignorance for performance testing in the industry, and being a top Software Testing Company in India, we are here to explain its significance.

    Generally, once the functional testing is approved, the team approves the code for release. But this should not be the case. Considering our testing experience, we have seen many cases where functional testing is approved but the issue has been found during performance testing.

    Hence one should always keep in mind, functional and non-functional testing are equally important. We believe, whatever technology has given us, has some potential and we should leverage them.

    Performance testing is included in the software testing lifecycle because it evaluates the final result, execution speed, transferring of data, bandwidth of the network, etc.

     Further, the testing method also ensures the performance of an application when a large volume of users starts using it at the same time. Workload efficiency and response time are properly monitored during performance testing.

    Importance of Performance Testing

    Analyzing a system’s performance is one the most important thing to check. And we know everybody will agree on it. Genuine and reliable testing companies in India always perform performance testing. Reasons that make performance testing mandatory:

    1. Performance testing determines the capability of an application for concurrent users up to 1000.
    2. Comparison is made in order to identify the better performer.
    3. Performance testing ensures the stability of a system in case of heavy traffic.
    4. Efficiency and Response time of application is also validated during performance testing.

    Considering these parameters, Performance testing becomes important. So, if you are really willing to maintain the potential and engagement of your business application, make sure to execute performance testing.

    Further, we have an excellent team of quality testers and we can assist you in the most prominent way. You can also hire a QA tester in India exclusive from QAble.

    What are the types of Performance Testing?

    Performance Testing verifies the system’s quality on various parameters hence different kind of performance testing is performed. Let’s elaborate on them.

    Load Testing: The objective of load testing is to determine performance bottlenecks prior to moving for production. During load testing, the capability of an application is checked towards a fixed user load.

    Stress Testing: No one can assume the volume of traffic on an application and hence there is a need to check an application under extreme workloads. During stress testing, handling of heavy traffic and data processing is checked.

    Endurance Testing: Endurance testing assures that software is capable of managing enough load for a long duration. Traffic can stay consistently on a platform hence testers are required to maintain the performance of an application under this scenario as well.

    Spike Testing: As the name says, this method of performance testing validates the performance of an application during sudden large spikes. This test is done to ensure that the system is able to take the sudden increased load.

    Volume Testing: During volume testing, the database is populated with a huge volume of data. The aim of volume testing is to check the application’s performance with a varying range of user volume. The scenario is most common and every application should follow the same.

    Scalability Testing: The ultimate aim of performance testing is to maintain the scalability of an application. The application must be efficient to manage the load and other execution processes with the required output.

    Some Common Issues of Performance:

    Performance testing highlights issues related to long load time, bad response, compromised speed, and bottlenecks. The most considerable feature is “Speed”. Being a user, we ourselves don’t like to use any application that is slow and takes time to respond.  As a result, users ignore such applications and all your effort is wasted.

    So, let’s discuss some common performance problems:

    Too much loading time: Whenever we start an application it loads first. And if load timing is too much, users get annoyed. Hence, developers keep it a minimum. An application with a faster loading time gets positive feedback.

    Bad response: Response is something that defines the level of interactivity of an application. If it generates a quick and accurate response towards the user’s input, the application is perfectly fine. And on contrary, users will lose their interest if it takes time or gives a wrong response.

    Compromised scalability: When an application is unable to manage or handle the expected user base, its scalability is poor. Hence an application must be tested and verified with the various number of users.

    Other Issues: Some common issues found during performance testing are CPU utilization, Network utilization, Memory utilization, Disk usage, and limitations with OS (Operating System).

    What is the Performance Testing Process?

    The process involved in software performance testing may vary depending upon the project’s need. But the aim is always the same. Further knowing the performance testing process enables testers to identify the accurate bug or the section that is affecting the performance.

    Below mentioned are the processes through which performance testing passes:

    1. Identify your testing environment
    2. Performance acceptance criteria identification
    3. Planning & designing of tests
    4. Test environment configuration
    5. Test design implementation
    6. Execute the tests
    7. Analyze, retest & approve

    Performance testing tools

    Knowledge of the right tools helps you to deliver accurate and fast results. Hence, we are sharing some preferred performance testing tools that are easy to access. However, you need to utilize these tools depending upon the project’s requirements.


    JMeter excels the loading time of an application by covering the genres of logic controllers, timers, thread groups, graphs, and functions. It is also compatible with IDE (Integrated development environment) to test browsers and web apps.

     Further JMeter is an Apache-based performance testing tool and it supports command line mode to test the load of Java-based platforms.


    Micro Focus has developed the LoadRunner performance testing tool. It evaluates the efficiency of an application under load. LoadRunner has the potential to accommodate the anticipated user-base and test the load.

    Also, the tool generates commands between end-users and components. It is the same as we press click and our mouse moves.


    Neotys is behind the development of Neoload. This performance testing tool facilitates stress and load testing for web and mobile-based applications. Moreover, NeoLoad is designed with the intent to identify the performance of the app prior to going for Develops or CD (Continuous Delivery).

    The attractive feature of Neoload is its capability to simulate millions of users. The testing can be done in-house or through the cloud. Neoload is flexible under various testing environments.


    We have covered all the aspects of performance testing that are important while analyzing the efficiency of an application. The era is too competitive and we should never leave any thread from where the performance can be compromised.
