Performance Testing

Performance Testing ensures that the software applications performs well under their expected workload. The goal of Performance Testing is to remove the performance bottlenecks.

Performance Testing determines the required area of improvement before the product goes to market.

It makes sure that an application is running fast enough to retain a user's attention and interest

It can help in comparison of the performance of two software or applications

Some Objectives of Performance Testing

1. It checks whether the application responds quickly and is fast enough for good user experience.
2. It tests the maximum user load the application can handle and how much it can scale.
3. It validates if the application is stable under varying loads or not.

Some Parameters of Performance Testing

• Processor Usage
