On their own, they would contribute little value as it is hard to discover new config variables. Instead, I've created this RFC as a goal for probably three sequential patch series: 1. (Patches 1-3) Introduce a new 'core.size' config setting that takes 'large' as a value. This enables several config values that are beneficial for large repos. We use a certain set in VFS for Git (see [1]), and most of those are applicable to any repo. This 'core.size' setting is intended for users to automatically receive performance updates as soon as they are stable, but they must opt-in to the setting and can always explicitly set their own config values. The settings to include here are core.commitGraph=true, gc.writeCommitGraph=true, index.version=4, pack.useSparse=true. 2. (Patches 4-8) Introduce 'status.aheadBehind' to dictate if we use '--[no-]ahead-behind' during 'git status' calls. Also do some cleanup on the feature around porcelain formats. I adapted Jeff Hostetler's commits from microsoft/git for this section. 3. (Patches 9-12) Introduce 'fetch.showForcedUpdates' and the associated '--[no-]show-forced-updates' option for 'git fetch' and 'git pull' calls. When fetching from a remote with many branches that move quickly, the check for forced updates can be expensive. Further, the only effects are a "(forced update)" indicator to stdout and a single bit in the reflog. The reflog bit is unfortunate to lose, but it is never trusted for important actions. These changes are likely to be more controversial than the others. Hopefully this direction is amenable to allow "early adopters" gain access to new performance features even if they are not necessary reading every line of the release notes.
