   1 feature.*::
   2         The config settings that start with `feature.` modify the defaults of
   3         a group of other config settings. These groups are created by the Git
   4         developer community as recommended defaults and are subject to change.
   5         In particular, new config options may be added with different defaults.
   6
   7 feature.experimental::
   8         Enable config options that are new to Git, and are being considered for
   9         future defaults. Config settings included here may be added or removed
  10         with each release, including minor version updates. These settings may
  11         have unintended interactions since they are so new. Please enable this
  12         setting if you are interested in providing feedback on experimental
  13         features. The new default values are:
  14 +
  15 * `pack.useSparse=true` uses a new algorithm when constructing a pack-file
  16 which can improve `git push` performance in repos with many files.
  17 +
  18 * `fetch.negotiationAlgorithm=skipping` may improve fetch negotiation times by
  19 skipping more commits at a time, reducing the number of round trips.
  20 +
  21 * `fetch.writeCommitGraph=true` writes a commit-graph after every `git fetch`
  22 command that downloads a pack-file from a remote. Using the `--split` option,
  23 most executions will create a very small commit-graph file on top of the
  24 existing commit-graph file(s). Occasionally, these files will merge and the
  25 write may take longer. Having an updated commit-graph file helps performance
  26 of many Git commands, including `git merge-base`, `git push -f`, and
  27 `git log --graph`.
  28
  29 feature.manyFiles::
  30         Enable config options that optimize for repos with many files in the
  31         working directory. With many files, commands such as `git status` and
  32         `git checkout` may be slow and these new defaults improve performance:
  33 +
  34 * `index.version=4` enables path-prefix compression in the index.
  35 +
  36 * `core.untrackedCache=true` enables the untracked cache. This setting assumes
  37 that mtime is working on your machine.
