Splitting the index (git update-index --split-index) doesn't work for me at all. While it may initially reduce the size of .git/index, making a commit inflates it back to its original size anyway.

I thought it might be some interaction with v4 index and its compression mechanics but it does the same if I set it to v3 index. For (manufactured) example:

    $ git update-index --split-index
    $ du -sh .git/*index*
    4.0K    .git/index
    76M     .git/sharedindex.70e661456302b51a7ec59bf5b32d630e74b34c7c

    ... add 8000 files ...

    $ git commit -m \"add files\"
    $ du -sh .git/*index*
    80M     .git/index
    76M     .git/sharedindex.70e661456302b51a7ec59bf5b32d630e74b34c7c
