How can you reduce resource requirements in JMeter?

Following are the tricks that help in reducing resource usage.

1. Use a non-GUI mode.

jmeter -n -t test.jmx -l test.jtl
2. It is better to use as few Listeners as possible. Applying the “-l” flag as shown in above point may delete or disable all the Listeners.
3. Disable the “View Result Tree” listener as it consumes a lot of memory and may result in JMeter tool running out of memory. It will freeze the console too. It is, however, safe to use the “View Result Tree” listener with only “Errors” kept checked.
4. Instead of using a similar Sampler a large number of times, use the same Sampler in a loop and use variables (CSV Data Set) to vary the sample data. Or perhaps use the Access Log Sampler.
5. Avoid using functional mode.
6. Use CSV output rather than XML.

7. Try to save the data that you need.
8. Use as few Assertions as possible.
9. Disable all JMeter graphs as they consume a lot of memory. All the real-time graphs can be viewed using the JTL tab in the web interface.
10. Do not forget to erase the local path from CSV Data Set Config when used.
11. Cleaning of the Files tab before every test run.
