A properly designed and executed load test is much more than slamming your system with its designed maximum traffic level. Sub-maximum levels can degrade performance without causing a disastrous crash. QualityLogic verifies your site’s performance at several load levels, both less than and above its design, by:

  • Creating from tens to tens of thousands of virtual users at stepped levels to simulate a variety of loads
  • Initiating load and performance testing through your user interface and directly at the API call level
  • Exercising multiple access paths in concert under graduated loads to verify a graceful failure
  • Documenting performance anomalies and degradations under all load levels
  • Coordinating with your IT group to instrument the server array during the test


ZenQ is a performance testing services provider company that helps you identify and fix issues early in the application development lifecycle. It enables you to prevent loss of revenue and reputation.

This firm has built a dedicated Centre of Excellence that researches and builds solutions for problems in different industries across various platforms.

Performance Lab

Performance Lab is a company that can test your application releases with ease on time. It uses unique automation techniques that help you to check the performance of a software using the Continuous Integration method.

This organization helps you to deploy software into a production environment. It offers a system that works on any device without any hassle. Performance Lab allows you to find out a limitation of the software.

This company performs autotest to release desktop, web, and mobile applications. However, it also performs a manual performance checking process to achieve a high quality of your software releases.


In this day and age, where competition between organisations is monumental, providing web, mobile apps & software without any performance issues is crucial. To ensure this, it is vital for organisations to invest in performance testing, which helps them meet the expected standards of software performance.

A type of non-functional testing, performance testing is an important part of software testing process. It tests the scalability, stability, & speed of an application under a specific workload and ensures high quality performance. Apart from determining how fast some aspects of a system perform under a particular workload, performance testing is also used to demonstrate that the developed system meets the performance criteria. Other features of performance testing are:

  • Authenticates the responsiveness, reliability, scalability, & other important features of an application or software.
  • Allows us to detect any discrepancies and rectify them before the release of the software product.
  • Enhances optimization, load capability, and capacity planning efforts.
  • Validates exceptional user experience, which further increases business revenue.
  • Identifies bottlenecks such as database configurations.


The reliable and consistent performance of your business critical applications is the key to success of your enterprise. However, performance issues within an application are often identified in live scenarios which result in considerable damage to the reputation of your brand. That is where formal web performance testing of the applications is necessary to ascertain application behavior at peak performance and scalability levels.

TestingXperts help you predict application behavior and performance in a simulated, real-life environment, thus saving you from unpleasant events later, which frustrate customers and impact profitability. We ensure the application is responsive and reliable enough to respond to peak load days like a black Friday sale and can also scale to other future events like product release, acquisitions, new clients, regulatory changes and ongoing business growth. We also ensure the applications can meet any
contractual obligations and SLAs for performance.


If you think that software testing can only help you to enhance the functions of your app and make it better, then you are mistaken. Yes, this might be one of the reasons, but definitely, this isn’t the only reason.

In Performance testing services, we try to find out the responsiveness, throughput, reliability, and scalability of your web and Mobile application under normal load and in stress condition at each stage of SDLC and before going to production. Here is how performance Testing can be beneficial!

  • Helps you for a comparative analysis between different software.
  • Can be a great alternative to determine whether your software system is working with a good speed during times of workload or not.
  • Reduce the front end costs by eliminating the bugs.
  • Assures you a better return on investment for seamless profit margins.

As a performance Testing Company we offer you software load and performance testing services as well as performance tests, website and mobile application load testing that test your app or website under normal load conditions as well as peak conditions.
