Ok, I see

So the art is finding the 'overhead'

I'll test a bit further tomorrow to find out when AddRange starts to be a better performer than foreach/Add

Thanks,


ps: Still - it's not what one would have expected

Update:

There should be less overhead in AddRange - I mean : it can start with finding out if sufficient space left in order to avoid the test fo revery item it adds
