How many time to process 7000 images?

Hi there, as per this thread*, 1000 images can take up to 8 days to be processed (!?).
Is this true?
Why isn't this explained when we purchase the pro version?
It obviousy is a ridiculous amount of time, so I wanted to make sure if I have to expect a proportional amount of time (56 days? lol...).

We have 7000 images to be processed. Did the time span needed to process them changed to something better lately? How long is going to take?
