So I have a 2011 Mac Mini with the 2.5ghz i5 and 5400rpm hard drive. Compared to my 2006 Mac Pro, which is scores 1,500 points higher than on geek bench, it starts to struggle a bit when throwing more things at it. The ram and processor usage seems OK, it's not maxing those out- I am thinking the issue is likely with my hard drive since it's only 5400, and I have an SSD in my Mac Pro. Is that it? Or is the dual core Mac Mini just not that powerful even with 8 gigs of ram?
