Conclusions

• The multi-layered image is even slightly smaller than the mono-layered one - so multi-layered image is even better when you download it once
• Downloading the image regularly by the users is way better in case of multi-layered image - for simulated user it's , downloading airflow image twice a week it is:  5.7 GB GB  (multi-layered) vs. 16.15 image GB (mono-layered) downloads over the course of 8 weeks.
