There is definitely room for improvement in delta base cache:
increasing cache size, better eviction strategies.. But I think it's
orthogonal to gc --aggressive improvement. From what Linus described
---aggressive is more for archival purposes but I think people have
been using it for upstream repos as well. Better packed repos could
speed up current clients immediately (although this argument is
somewhat flawed, server updates are usually at slower pace than
clients..).
