Yes, the 5 million photons is the total number of photons shot: the more 
you have diamonds, the less each will "get" photons. You can get around 
this by using the "spacing" keyword instead - then the number of 
diamonds don't matter. Read the section 6.10.2.1 for more information on 
this. You might also want to specify "collect off" for each diamond - 
that might make the rendering (maybe also the parsing) faster.
