The 99% for SSE2 comes from the Firefox crash reports, where the large majority are for very recent Firefox downloads. If you can identify SSE3 machines from the reported CPU string (as the Firefox people did for SSE2), please do have a look a see if you can get a count for SSE3 in the Firefox crash reports; if it's close to 99% that would make a strong argument: https://github.com/numpy/numpy/wiki/Windows-versions#sse--sse2 https://gist.github.com/matthew-brett/9cb5274f7451a3eb8fc0 Cheers, Matthew _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
