If you are trying to see which commits changed the most files (and/or
lines), you may find
   git log --oneline --shortstat
helpful.  A quick search through that output may help you decide where
to dig further.

Also, I'm sure someone else here probably has a better idea, but here's a quick hack I came up with to look at "commit sizes":

mkdir tmp && for i in $(git rev-list --all); do git branch -f dummy $i && git bundle create tmp/$i.bundle dummy --not dummy^@; done

Follow that up with a quick "ls -alrSh tmp/" and you can see the "size" of each commit.

Hope that helps, Elijah
