see START/STOP_TIMER
they provide quite precisse timing
also make sure all asm optims are used and theres no difference in
thread settings
also if you use swscale make sure it too uses the asm

and please report your findings even if it turns out to be a bug in
your code so noone else wastes time investigating this
