5 sec * 2300 packages = 11,500 sec
11,500 sec is 3.19 hours

3.19 hours * many builds is equal to days and weeks.

The 5 sec is your guess, probably less but ...  Minutia ends up being
quite a large sum when you repeat a process over and over.

The 2300 packages is a round of the number of packages Yaakov supports.
