Many companies develop their own applications to connect with customers and to streamline their business operations. Banking portals, online shopping platforms, project collaboration software, and even web-based games are some examples.
If you’re currently developing one, you need to make sure that it undergoes Java performance testing. This assures that the application will perform well considering its expected workload. Testing will also help you address issues with the application’s performance.
Why Test the Performance of Applications
Performance testing focuses on checking an application’s speed, stability, and scalability. This way, any problem concerning these three can be resolved right away before the application is used by the public. If these problems are not identified and fixed immediately, users may lose interest in the program, have a difficult time using it, or not use it at all.
The Common Issues in Application Performance
Here are some of the common performance problems that your software development team should watch out for and address in your application.
- Slow load time – Load time refers to how long it takes an application to start. A long load time should be avoided, as users may lose interest and look for another application to use.
- Long response time – Response time refers to how long it takes an application to show a response when users input data into it. Like load time, response time should be as quick as possible.
- Bottlenecks – A bottleneck in a system is an obstruction that decreases overall performance, and is often caused by coding errors. Bottlenecking can happen in how the memory, network, hard disk, or CPU resources are used, or when there are limitations in the operating system that hinder processes from running smoothly.
- Poor scalability – If the application cannot handle or manage the anticipated number of people using it at the same time, it has poor scalability.
The Kinds of Performance Testing
The issues above can be identified through the following types of performance testing:
- Load testing – This identifies bottlenecks by checking the application’s ability to perform under expected user loads.
- Endurance testing – Checks if the application can handle the anticipated load over a long period.
- Scalability testing – Determines how effective an application is when it has to scale up to support a bigger user load.
- Stress testing – Identifies an application’s breaking point by testing it under extreme workloads.
- Spike testing – Checks how the application reacts to a sudden spike in user load.
- Volume testing – Monitors the application’s performance when handling a large number of data.
Knowing how your application performs is necessary so problems can be addressed before making it available for wider use. This will make sure you provide a good user experience, which increases the chances of your application seeing more satisfied users or being a more valuable tool for your business.
