It's different data Jeff.
It is the results of running speed (which now works under Windows) as
follows:
speed -c -s 1-40 mpn_add_n
speed -c -s 1-40 mpn_addmul_1.333
speed -c -s 1-40 mpn_mul_1.333
speed -c -s 1-40 mpn_lshift.23
speed -c -s 1-40 mpn_rshift.23
speed -c -s 1-40 mpn_lshift1
speed -c -s 1-40 mpn_rshift1
speed -c -s 1-40 mpn_mul_basecase
speed -c -s 1-40 mpn_sqr_basecase
(I have only reported two of these results).
I will happily add results if you are able to provide them for Core 2
on either or both Linux and Windows.
