Performance Testing is a process of analyzing the speed, response time, stability, scalability, and resource usage of a software application under a particular workload. The main purpose of this method is to identify and eliminate the bottlenecks in the software application. It is a subset of performance engineering and also known as “Perf Testing”.

Here are some of the Best Performance Testing Service Companies:

Here are the important benefits of performance testing:

  • Provides information to stakeholders: Performance Testing is done to provide stakeholders with information about their application regarding speed, stability, and scalability. Without Performance Testing, the software is likely to suffer from issues such as: running slow while several users use it simultaneously, inconsistencies across different operating systems, and poor usability.
  • Determines the requirement under workload: Performance testing determines whether the software meets usability and stability requirements under expected workloads. Applications released in the market with poor performance metrics due to nonexistent or poor performance testing are likely to gain a bad reputation and fail to meet expected sales goals.
