Hello !

I would like to have some help on the following question: is there any advantage or optimization given by the O3 flag when compiling opencv 2.4.11? The official version compiled with O2 works perfectly but I would like to know if the try was worth the time spent. I plan to use it for embedded work and every ms gained is interesting!

Thank you in advance for your help and answer, kgexo
