Shell script to optimize a git repo for many files

git_repo_setup.sh

#!/bin/sh

# Enable Git optimizations for repositories with many files.
git config feature.manyFiles true

# Update the index format to version 4 for better performance with large repositories.
git update-index --index-version 4

# Enable filesystem monitoring to speed up `git status` and similar commands.
# This uses the built-in fsmonitor on supported systems, reducing the need to scan the entire working directory.
git config core.fsmonitor true

# Enable caching of untracked files to speed up commands like `git status`.
# This avoids repeatedly scanning for untracked files.
git config core.untrackedCache true

# Enable commit graph for faster operations like `git log`, `git blame`, and `git rebase`.
# This precomputes and stores a graph of commits.
git config core.commitGraph true

# Automatically update the commit graph during `git fetch`, keeping it in sync with the latest changes.
git config fetch.writeCommitGraph true

# Optional: Enable sparse-checkout if working with very large monorepos.
# This allows you to check out only a subset of the repository.
# git sparse-checkout init --cone
# git sparse-checkout set <desired-directory>

# Optional: Enable parallel fetch and clone operations to speed up these processes.
# git config --global fetch.parallel 4

# Optional: Set the pack compression to a lower level (faster) during fetch and push operations.
# This is useful in very large repositories. Not recommen ded for development!
# git config pack.threads "1"
# git config pack.windowMemory "100m"

# Optional: Adjust the garbage collection settings to run less frequently.
# This prevents slowdowns during frequent commits or fetches.
# git config gc.auto 1000
# git config gc.autoPackLimit 1000
