Git and Mercurial - can someone explain this test result

I did a speed comparison for GIT and Mercurial.
I choose a large project of 9072 files (mainly php files and several images) of 95.1 MB in size.

This is a fake project and perhaps gives someone an idea on how to explain the results that I got - to download, without changes, and copy 12 times into two folders - one for GIT and another for the Mercury repository.

Then I create a GIT repository and commit (using TortoiseGIT), and upon completion, I did the same in another folder for Mercurial using TortoiseHG.

Git Results
Time: 32 minutes and 30 seconds to complete everything
Repository size: 6.38 MB, a total of 847 files.

Mercury results:
Time: 1 minute and 25 seconds - yes, only 1 minute.
Repository size: 58.8MB with 9087 files.

I am not saying that it’s best or something else, I’m just trying to understand the differences and how SCM created the repositories.

It seems that HG made a copy of the files with some kind of compression.
But I don’t understand what GIT did.
Can someone explain the results?

PS: I know that there are already several questions about GIT and Mercurial, I'm only trying to find out the result of this test - and even if it is a valid test. When I started, I only checked the speed, but I have some question marks on my head ...
