oops, meant 2.7G not 8.5G there ... sorry, was working from memory.

1.3G .git

the difference between 2.7G and 2.8G may be due to filesystem difference?

1.3G is the packed size ...
jp3@electron: ooo(unxsplash)>ls -sh .git/objects/pack/
total 1.3G
37M pack-87efcac9bcb117328e8a1b0c1b42c88c3603c5b7.idx
