Does speed step work for me or not?

Question

macOS

Hello, I'm interested in such a question,
In OSX, everything is very bad with flash.
I have Windows 7 installed on one hard drive and several windows + flash or Ace stream player are open and the processor load does not rise above 2 Ghz.
At the same time, OSX 10.10.5 installed on the second hard drive, if you run a flash, the processor load rarely drops below 3Ghz, and despite the fact that half as many windows are open. Is it possible that the speedstep is not configured correctly? or OSX is such a demanding OS.
PS! looked only two or three mac models have a processor (i3) the rest have either i5 or i7
Processor Core i3 4170 2 cores and 4 threads
Computer parameters
Core i3 (3.7Ghz, 4170), 4Gb DDR3
If anyone can upload a video of the processor on a poppy with the intel Power Gadget utility program for different loads.
