Ok, so I'm feeding them from latest to oldest along each branch, which optimizes only the 'master' branch, leaving other branches much further down in the data file. That should mean repacking will help a lot for repositories with many active branches. > In that case it > might be preferable that the reuse of already deltified data is made of > backward delta which is the reason you might consider feeding object in > the prefered order up front. Hmm. As I'm deltafying along branches, the delta data should actually be fairly good; the only 'bad' result will be the sub-optimal object ordering in the pack files. I'll experiment with some larger trees to see how much additional savings the various repack options yield. -- keith.packard@xxxxxxxxx
