Guidelines to overcome limitations of JMeter in a distributed environment:
Limit the Number of Threads
Using a proxy server
Using variables
Reduce resource requirement
Check the JMeter logs
Erase the local path from CSV Data Set Config
Follow file naming convention
Using a proxy server
The Proxy server helps you to abstract out certain common elements from the recorded samples. Moreover, it is useful features to record your testing.
Using variables
Some test plans need to use different values for different users/threads. For example, you might want to test a sequence that requires a unique login for each user. This is easy to achieve using variables.
Reduce resource requirement
The GUI mode consumes a lot of computer memory under heavy load. It causes performance issues.
There're some tips to reduce resource requirement:
Use non-GUI mode
Disable the "View Result Tree" listener during the Load test. Because it consumes more memory and causes JMeter running to run out of memory.
Disable all JMeter graphs results
Use the CSV test result format.
Only save the needed test result. JMeter could take a long time to save very detailed test results.
Check the JMeter logs
Any errors in the Test Plan or test execution will be recorded in the log files. Monitoring the log file help you to find the error early
Erase the local path from CSV Data Set Config
If you are using an existing CSV data file that you created on your local computer, you should delete the existing local path (Current path of CSV file). If you don't delete the local path, JMeter cannot find the CSV data file on your local PC.
Follow file naming convention
Don't save test plan under complex file name, use only alphanumeric characters.
