For many reasons, but two really obvious ones: - pack-file indexes get read in on startup, and we maintain an explicit list of them. Having lots of pack-files adds overhead that doesn't exist for lots of loose objects. - loose files are spread out over 256 subdirectories to make lookup easier, packfiles are not (and always create an index file too). So in general, as a trivial heuristic, you probably want about 512 times as many loose objects as you want pack-files, i fonly because of the latter issue, because you can much more easily handle lots of loose objects than lots of pack-files. So it's _not_ a factor of 3. Or even 10. But since there _is_ reason to do pack-files too, and since using too big a value means that you never end up keeping a pack-file _at_all_ if you pull often, I'd suggest that rather than use a limit of 512 you go for something like 100-200 objects as the threshold (of course, the proper one would depend on the distribution of the size of your pack-files, but I'll just hand-wave and say that together with occasional re-packing, something in that range is _generally_ going to be a good idea).
