Whipped some up for you: Repo Operation master after delta arch-packages ../git/git-log 2.26 2.27 -0.01 arch-packages ../git/git-log -- zzzzz_not_exist 34.69 26.75 7.93 arch-packages ../git/git-log -- aaaaa_first 6.02 5.76 0.26 linux-2.6 ../git/git-log 5.51 5.50 0.02 linux-2.6 ../git/git-log -- zzzzz_not_exist 0.95 0.92 0.03 linux-2.6 ../git/git-log -- aaaaa_first 0.89 0.86 0.03 These are all the "real" value from time with the full set of patches applied. As you can see, one either gains or isn't really affected by these; anything under 0.05s delta is noise. Bigger gains than this don't seem too plausible unless we move away from linear parsing and traversal of tree objects. -Dan -- 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
