Nico, if you have time you may want to look into this. The result v4 pack from pack-objects on git.git for me is 35MB (one branch) while packv4-create produces 30MB (v2 is 40MB). I don't know why there is such a big difference in size. I compared. Ident dict is identical. Tree dict is a bit different (some that have same hits are ordered differently). Delta chains do not differ much. Many groups of entries in the pack are displaced though. I guess I turned a wrong knob or something in pack-objects in v4 code.. -- DUy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
