Performance Testing

Performance testing is an important non-functional testing of the software testing process. It tests the stability, scalability, and speed of any application beneath a particular workload and makes a certain high-quality performance. Additionally, it is used for demonstrating that the developed system meets up the desired performance criteria.

At ITQCR, outstanding performance is guaranteed as we deliver end-to-end performance and the finest testing services ensuring robustness, availability, scalability, reliability, and optimum speed of our clients’ systems and applications.

For the success of our clients’ business, our experts ensure the responsiveness, reliability, and consistent performance of your desired business-critical software applications and secure system performance.


Linear scalability – where an application’s performance does not vary as the number of users increases – is the Holy Grail of Web application testing. Load testing identifies a Scalability Index for your Web application performance.

  • Check server response to browser form submit requests
  • Identify performance changes over a period of time
  • Test for functions that stop working at higher levels of user load
  • Identify the network latency problems on Web application function


  • Determine how the application responds under high levels of load
  • Identify portions of the Web application that fail under high levels of load
  • Identify application function after a system crash or component failure
  • Identify forms and links that operate differently under high levels of load


Soak Testing also known as endurance testing, is performed to determine the system parameters under continuous expected load. During soak tests the parameters such as memory utilization is monitored to detect memory leaks or other performance issues. The main aim is to discover the system’s performance under sustained use.


Spike testing is performed by increasing the number of users suddenly by a very large amount and measuring the performance of the system. The main aim is to determine whether the system will be able to sustain the work load.
