When we clone a remote we get we get instead of object packed files which seems to be some performance optimization to reduce size.
But how is this optimization done? If I understand these are binary files with the same contents as the original objects so how exactly they occupy less space? Is the implementation some standard one?

  • Maybe you don't get the deleted refs? – biziclop Dec 20 '16 at 20:57

    Because they are compress? Why `C` tag? – Stargateur Dec 20 '16 at 20:57
  • @Stargateur:Git is written in C right? So maybe it is about the way we write binary files in compact manner in C? Some standard pattern? How are they compressed? – Jim Dec 20 '16 at 21:09

As I mention in "How does git store files?", Git does use deltas for storage.

The result includes pack files, using a custom implementation of a diff algo for delta computation.
