   1fastimport.unpackLimit::
   2        If the number of objects imported by linkgit:git-fast-import[1]
   3        is below this limit, then the objects will be unpacked into
   4        loose object files.  However if the number of imported objects
   5        equals or exceeds this limit then the pack will be stored as a
   6        pack.  Storing the pack from a fast-import can make the import
   7        operation complete faster, especially on slow filesystems.  If
   8        not set, the value of `transfer.unpackLimit` is used instead.
