git blame does not spend that much of its time diffing.  Even if the
difference between plain and -w has become larger with Git 2.1+ (simply

rather than comparing them.

Would you consider this kind of difference of no consequence?

$ time git blame src/xdisp.c >/dev/null

real    0m11.875s
user    0m10.753s
sys     0m0.583s
$ time git blame -w src/xdisp.c >/dev/null

real    0m17.127s
user    0m16.779s
sys     0m0.356s

If you use a Git version older than 2.1

2.1.0 here.

But anyway, I distinctly remember the performance of blaming being one of the reasons why we shouldn't do whitespace-cleaning across the repository.
