Extract from test_Loading on the N900:
        benchmark:
http://cs.nyu.edu/courses/fall02/V22.0201-001/nasm_doc_html/nasmdocb.html
                mean:     1043 msecs +/- 4 msecs, +/- 0,383509 %
                avg:      1042 msecs
                        1050, 1045, 1038, 1040, 1039, 1043, 1046, 1042, 1036
        benchmark:
http://cs.nyu.edu/courses/fall02/V22.0201-001/nasm_doc_html/nasmdocb.html
                mean:     1030 msecs +/- 3 msecs, +/- 0,291262 %
                avg:      1030 msecs
                        1035, 1036, 1025, 1026, 1030, 1032, 1032, 1026, 1029

Given the variance, it is a <1% improvement.
