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?
