Sorry for not being clear but the point of this thread was to find out how to obtain performance numbers. With that information I would obtain the numbers for Win 10, reinstall Win 7 and obtain those numbers again to allow comparison.
A stopwatch.
Multiple repetitions of the same procedure, and average the time.
However, you'll run into repeatability concerns. Are both systems running the exact same software? All the background processes the same?
Same browser version, etc?
Flushed the browser cache after every test?
Any hardware limitations? Win 10 is slightly lighter on the hardware, so if the RAM is limited, for instance, that might give a nod to Win 10.
And "loading a webpage" introduces variables beyond your control...network performance at that moment.
But from my personal experience with 7/8/8.1/10...I doubt you'd see more than a 5% difference, in either direction.
For me, though...Win 10 feels a teeny bit faster. Totally subjective, though.
