Whether launching a new eCommerce store or managing an existing one, having key performance indicators (KPIs) to measure success is paramount. Knowing which KPIs are most relevant and how to test them properly will help ensure that your application performs correctly & meets user expectations. Bahaa Al Zubaidi looks at some select KPIs that all eCommerce businesses should consider when evaluating their application’s performance.
What is the purpose of performance testing?
Performance testing is a type of software testing that evaluates the performance and scalability of an application or system. This testing determines how well an application performs under certain conditions, such as heavy load, different user numbers, and various usage scenarios. Organizations can identify potential issues by running performance tests before releasing their applications into production environments. This helps ensure that their applications can handle high traffic and usage levels and provide acceptable response times.
Common KPIs to consider for performance testing
Performance testing is key to ensuring software applications run optimally and efficiently. To ensure this, performance testers need to analyze Key Performance Indicators (KPIs). Common KPIs used in performance testing include:
1. Response Time
Response time measures how long a program responds to user input. Performance testers should monitor this KPI closely as it can indicate how well an application is running.
2. Throughput
Throughput measures the rate at which a system or network can process data packets over time, such as requests per second. Monitoring throughput can alert testers to potential issues that could slow down an application.
3. Memory Usage
Tracking memory usage helps testers identify any memory leaks present in the software, which can cause it to run slowly. It can also help identify any potential bugs or technical issues.
4. Usage
CPU usage tracks how much processing power the application requires to run. High levels of CPU usage can indicate a problem with the application’s code and signal that it needs to be optimized.
5. Load Testing
When applications experience high loads, they often slow down or crash. Load testing is a performance test that simulates how an application responds to large amounts of data or traffic, allowing testers to identify any potential problems before they occur.
6. Error Detection
Performance testers also need to monitor for any errors or bugs that could be present in the application’s code. Monitoring error logs and analyzing log files helps testers quickly identify and address any issues.
7. User Experience
Performance testers should also consider the user experience when testing. This includes examining usability, response times, and overall application satisfaction.
Conclusion
By taking into account different KPIs during performance testing of eCommerce applications, a more holistic overview can be achieved that includes not just the response time of the servers. But also how users interact with the application. This helps identify issues that may not be immediately apparent and provides a better platform for future development and releases.
