Java memory usage setup for Controller and LG on same system

I am configuring on Controller System that will also act as the LG "localhost". I am wondering about the settings for the java usage memory.

If I set NeoLoadGUI.vmoptions to use "-XX:MaxRAMFraction=2", does this cater for the LG as well? Or do I need to set that elsewhere? I found this article outlining the LG settings in 'agent.properties' but my assumption this is for the LG installed standalone as a service.

Can you please confirm that setting LG '-XX:MaxRAMFraction=2' will make that memory available for both Controller and LG processes?

No the mentionned setting is for the Controller only. To modify the LG settings, you need to edit the agent.properties file ([LoadGenerator]lg.launcher.vm.parameters), in <neoload>/conf for the independent LG and also for the embedded Agent.

Thanks Christophe. So, confirming that this means both the embedded LG and the Controller use up to the mentioned RAM? So using the flag -XX:MaxRAMFraction=2 for both is not advised? (that is half+half = all the memory available?)

You'll get more fine tuning possibility by specifying explicitly the maximum amount of allocated RAM, remove -XX:MaxRAMFraction and replace with -Xmx800m where the number is the number of allocated MB.
