The search always start with the pack where the last object lookup succeeded. If the wanted object is not available there then the search continues with the normal pack ordering.
Nice numbers for performance, especially your later email showing this makes split packs almost as quick as one pack.
Note: the --max-pack-size to git-repack currently produces packs with old objects after those containing recent objects. The pack sort based on filesystem timestamp is therefore backward for those. This needs to be fixed of course, but at least it made me think about this variable for the test.
Yes, I was intending to submit a patch to builtin-pack-objects.c to reverse the timestamps when split packs were created. Haven't got around to it yet. -- Dana L.
