JMeter offers users a straightforward and user-friendly GUI. The user can use elements like Thread Groups, Samplers, Processors, Controllers, Timers, etc. to build their performance test script.
JMeter GUI mode additionally provides the ability to view and examine the script’s outcome utilizing various Listeners.
In addition to the mentioned features, JMeter GUI mode has the following drawbacks:
- Running JMeter in GUI, Java will favor the AWT Event Dispatcher Thread used to render GUI vs Threads running JMeter test
- Monitoring a JMeter performance test in GUI mode requires adding
- When a test plan includes complicated test scenarios with several test steps and operations, JMeter GUI mode consume a lot of CPU and memory, which has an impact on the test results.
- The system will also slow down if more Listeners are added to the Test plan.
To avoid above issues and get the optimal results, you must run your JMeter scripts in Non GUI mode at the expense of analysis efficiency.
