We have now had the SHA-1 reworked by JimF. I believe the "para" values you collected will work fine but ideally you should run that again if/when possible (I presume it was scripted :) The latest testpara also compares old 80x4 SHA-1 intrinsics and new 16x4 one (but so far the new code is faster in all situations). For 32-bit builds, it also shows the asm versions' speeds. magnum
