up on the top left of the app, click file > preferences. make sure its running the maximum amount of threads. if its not click on the check box that says custom and just set it to its max. If that doesnt work you could check your power settings in windows and make sure its running at max performance. If not press ctrl+shift+esc to open up task manager, go over to the details tab and right click cinebench and go to priority and mess around with that, i think its set to below normal on default.
