Performance testing evaluates a software application's responsiveness, stability, and overall system performance under varying load conditions. It aims to identify bottlenecks and ensure that the application is production-ready by analyzing speed, scalability, and reliability. Common performance testing tools include JMeter, LoadRunner, and SmartBear, among others.

Performance testing is a non-functional type of testing and involves the process by which a
software or an application is tested to know its current system performance. It checks how your
current system performs in terms of responsiveness and stability when tested under varying
workload conditions. Effectively, the system is tested under multiple and different load
conditions and it scrupulously checks the time taken by the system to respond under these loads.
There is a fear with respect to how an application or a demanding software performs under
varying loads when it goes live. Under such situations Performance testing actually measures the
Speed, Scalability, Reliability, Robustness and Stability of the application when the system is
tested for varying loads of users.

HOW DOES PERFORMANCE TESTING COME AS A SAVIOUR?
Primarily Performance Testing Evaluates the below:
Further to the above, Performance Testing also accomplishes the below:
Performance Testing
A Complete Guide
Software Bottlenecks - Issues with DB queries, Application integrations etc.
Hardware Bottlenecks - Shortage of RAM, Disk and CPU resource usages
Network Bottlenecks - Transmission medium’s limitations
Bottlenecks with Test Environment - Performance test environments tend to be
smaller versions of the production environment
Issues at times with an unrealistic user behavior
Another constraint is only a Subset of Functions can be automated at any time
Systems Deliver Good Speed (Reliability)
Systems Perform well, even with millions logging into the system (Scalability)
Whether your application is an E-commerce website or a mobile app or any other system, it
should be well tested to show effective response times. It is an important factor for all
business applications to handle the real time traffic for which performance testing should be
taken up with some of the latest performance testing tools.
