Jupiter Core slowing down website


With the actual Jupiter X Version my Site is running slow as hell. Doesn’t matter if i take a look at the backend or the frontend. If i deactivate the Jupiter X Core plugin eveything is fine - except frontend, which is white screen. Doesn’t i get it right, that jupiter plans do get rid of the plugin anyway? What can cause this issue?

Maybe someone can help me out with some tipps on this.
