In jmeter bin folderas per jmeter doc in Jmeter.bat file we can set the heap memory size for windows. But there is another file jmeter without extension has also heap memory size setting.
# system's memory availablity: HEAP="-Xms512m -Xmx512m"
What is the purpose of it here? If we set in jmeter.bat file do we need to set in jmeter without extension file as well?
