Should these servers run periodic and explicit gc/prune?
At least pack files wouldn't accumulate. This is the major cause of slowdown, since each pack file must be checked for each object. (And, also, maybe those unreachable loose objects are too new to get gc'd, but if we retry next week, we'll gc them).
