This interesting web site provoked some questions. 1 How risky is it to leave WebGl turned on in Safari? Some other popular browsers seem to have it on by default. http://sci.esa.int/where_is_rosetta/ Safari seemed to load and run this page more efficiently than Chrome or Firefox. My mini did not spin the fan up so much after I decided to enable WebGl to try Safari for this page. In fact, the difference between Safari and the other two browsers was more than 1000 RPM. 2. Is this effect unique to my 2012 i7 or if other users encounter similar differences on power hungry pages? 3. How do dual core machines perform with this website? I wonder if a 2014 Mac mini will benefit from improved video performance or suffer any deficit because of CPU configuration. Use your mouse to tilt the plane of the Solar System and provide a different view. That comet has this mini humming.
