Serialize methods in python + zlib levels - benched on Xeon E5-2658

I am storing python(Python 3.6.1) dict data in mongodb and tested serialisation methods on Xeon E5-2658 v4. For testing i used 10hours of my data as a python dictionary.

When handling big data it is important to be time/size efficient. Just want to share here what i found out...

suggestions are verry welcome....
