i set up this scene originally to test an emitter light set i built, similar to a photographer's portrait studio setup with selectable side, rim, & front lights. though the lighting looked spectacular & was the effect i was aiming for, even after 24 hours it hadn't cleared up much. i added a sun/sky & tried that, disabling all the emitters in Lux, but still had too much noise . so i delected all the emitters & left a simple sun/sky setup, & within 30 minutes it had cleared up nicely with little noise. which tells me that even the presence of disabled emitters in your Lux scene impacts render time.
