* `fetch.negotiationAlgorithm=skipping` may improve fetch negotiation times by
skipping more commits at a time, reducing the number of round trips.

-* `fetch.writeCommitGraph=true` writes a commit-graph after every `git fetch`
-command that downloads a pack-file from a remote. Using the `--split` option,
-most executions will create a very small commit-graph file on top of the
-existing commit-graph file(s). Occasionally, these files will merge and the
-write may take longer. Having an updated commit-graph file helps performance
-of many Git commands, including `git merge-base`, `git push -f`, and
-`git log --graph`.

* `protocol.version=2` speeds up fetches from repositories with many refs by
allowing the client to specify which refs to list before the server lists
them.
