Key metrics for measuring Java application performance include: Response time: The time it takes for the application to process a request. Throughput: The number of requests an application handles per second. Resource usage: CPU, memory, and GC time consumed by the application. Concurrency: The ability of an application to handle requests simultaneously. Exceptions: The number and type of exceptions thrown by the application.
Indicators for measuring the performance of Java applications
1. Response time
System.currentTimeMillis()
or JMX
. 2. Throughput
3. Resource usage
jstat
command to monitor these metrics. 4. Concurrency
5. Exceptions
Practical case:
Measure the throughput of the sample application using JMeter:
By analyzing these metrics, developers can gain insight into the performance of their application and identify areas for improvement.
