Performance Metrics
Performance Metrics
A Performance Metric is a measurable value that indicates how well a system, process, or software application is performing. For effective performance testing, it is essential to focus on several key performance metrics that provide insights into the system’s behavior:
Response Time
Measures the time taken by the system to process a transaction or request. Lower response times indicate better performance.
Throughput
Indicates the number of transactions processed per second or minute. Higher throughput demonstrates the system’s capability to handle high volumes of transactions.
Concurrent Users
The number of users that can simultaneously access the system without significant performance degradation.
Error Rate
The percentage of transactions that result in errors during testing. A low error rate is indicative of a stable system.
Resource Utilization
Monitoring CPU, memory, disk I/O, and network usage helps in understanding if the infrastructure is sufficient or if upgrades are necessary.
