From git-gc(1):
If the number of loose objects
exceeds the value of the gc.auto configuration variable, then all
loose objects are combined into a single pack using git repack -d
-l.
...
If the number of packs exceeds the value of gc.autopacklimit, then
existing packs (except those marked with a .keep file) are
consolidated into a single pack by using the -A option of git
repack.
...
The optional configuration variable gc.aggressiveWindow controls how
much time is spent optimizing the delta compression of the objects in
the repository when the --aggressive option is specified. The larger
the value, the more time is spent optimizing the delta compression. See
the documentation for the --window' option in git-repack(1) for more
details. This defaults to 250.

git gc --aggressive spends most of its time in git repack calls.  Still, using 
higher depth and/or window should shrink the packs and using lower depth 
and/or window should grow the packs.
