Hardware and performance

Hi,
I am using JMeter version 5.6.3 and have created a test plan in Moodle to evaluate performance. However, during execution, I encountered an error indicating that the file 'recorder.bsf' was missing. After replacing it with 'BeanShellFunction.bshrc', the error no longer appeared. I want to confirm whether this is the appropriate solution and does not affect the performance test results.
I tried using a lower version (2.11) of JMeter, but it gave an error related to PermSize because I'm using a higher version of Java. I do not want to install a lower version of Java and use an older version of JMeter, so I'm looking for another solution.

Thanks.
