W10 runs fine on my laptop, a Thinkpad T440 with an i5-4300U, 8GB RAM and SSD.
W10 does a fair few things wrong, but performance is not really one of them, unless you're on a Pentium 4 or something.

Windows seem to require many many CPU cycles just to update itself and index files (yet cortana never seems to find anything, but that's another discussion).
