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. :)
Thanks.
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.
Hmmm.... So you observe the same as me. Spirit2 ~1000% faster than the basic libraries as opposed to 25% faster from the previous tests. "Curiouser and curiouser" said Alice. -ed ------------------------------------------------ "No more boom and bust." -- Dr. J. G. Brown, 1997
