With hashing, it should be able to more quickly identify just the subdirectories that contained changed files, by the directory mtimes. + +And the real kicker is that when committing there, git has to create a tree object containing every single file, even if only 1 file changed. That will be a lot of extra work; with hashed subdirs it will instead create just 2 or 3 small tree objects leading down to the changed file. (Probably these trees both pack down to similar size pack files, not sure.) +"""]] |
