change the unpack limit treshold to a saner value
Currently the treshold is 5000. The likelihood of this value to ever be crossed for a single push is really small making it not really useful. The optimal treshold for a pure space saving on a filesystem with 4kb blocks is 3. However this is likely to create many small packs concentrating a large number of files in a single directory compared to the same objects which are spread over 256 directories when loose. This means we would need 512 objects per pack on average to approximagte the same directory cost (a pack has 2 files because of the index). But 512 is a really high value just like 5000 since most pushes are unlikely to have that many objects. So let's try with a value of 100 which should have a good balance between small pushes going to be exploded into loose objects and large pushes kept as whole packs. This is not a replacement for periodic repacks of course. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
