Hi, I recently noticed that `git maintenance run --auto` always ends up repacking loose references. This is because the "files" backend does not yet have any heuristics wired up to decide whether or not packing refs is in order. The consequence is that we always decided to pack them, which is of course quite a waste of time. This small patch series fixes this by introducing a new heuristic for the "files" backend. The heuristic is rather simple: the bigger the "packed-refs" file, the more loose refs we require before we decide to repack. We have been using this heurisitc successfully for a long time in Gitaly by now. Thanks!
