I opened a new thread called "Timings for bswap, ror, imul, push+pop vs mov [esp+x], nnn, lodsd vs mov eax,.." in the Lab :cool:

Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz (SSE4)

23      cycles for 100 * imul 10
54      cycles for 100 * lea: *10
4871    cycles for 100 * lodsd (25 DWORDs)
4863    cycles for 100 * mov eax, [esi] + add esi, 4
58      cycles for 100 * lea10, add eax
57      cycles for 100 * lea10, shl eax, 1
27      cycles for 100 * bswap
62      cycles for 100 * ror 16
