Perhaps you could try a more canonical test - running "ejg_uint_parser_0_0_4.cpp"
That does not make use of boost::bind - but tries to avoid the optimizer getting rid of void(void) functions by using globals.
I have no clue why I am still awake, brain is already shut down, code is a blurry blob to me right now, but I still compiled and ran your latest file. :) The results: initializing input strings... Calibrating overhead......done Timer overhead (t_c) ~= : 12 Jitter ~= : 8.43769e-015 qi_parse vs atoi : 1381.05 1385.57 1389.6% faster. qi_parse vs strtol : 1365.82 1389.6 1597.94% faster. strtol vs atoi : 1.03202 1.04052 10.6428% faster. qi_parse vs qi_parse : 0 0 0% faster. Checking that the results are correct... atoi is behaving itself! strtol is behaving itself! qi is behaving itself! All done!
