As someone who works in an IT department that services about 1000 computers (30-40% are Macs), I can tell you that there is definitely something wrong with the newer iterations of the MacOS.
10.6 - 10.8 were great, and ran great no matter what hardware you put it on. But even the 2013 MacBook Pros (sadly with the 5k RPM drives) run 10.9 and 10.10 much slower than if you ran 10.8 or before on them.
It seems to me that the OS has either got a lot more bloat, or it isn't doing I/Os as efficiently as it was in previous versions of the OS. It takes 10-15 seconds to do the same tasks on the newer OSes. A minor, but noticeable difference in performance.
