This series is meant to replace the RFC discussion in: https://public-inbox.org/git/20180808231210.242120-1-jonathanta...@google.com/
and https://public-inbox.org/git/20180808155045.gb1...@sigill.intra.peff.net/ The general idea is that accessing objects in packfile order is way kinder to the delta base cache, and thus way more efficient. See patches 4 and 7 in particular for discussion and numbers. I'm primarily interested in cat-file, so this series is focused there. But there may be other callers of for_each_packed_object() who could benefit. Most of the existing ones just care about getting the oid, so they're better off as-is. It's possible the call in is_promisor_object() could benefit, since it calls parse_object() on each entry it visits. I didn't experiment with it.
