This chapter focuses on optimizing Git for large repositories, where handling massive files, numerous branches, or extensive commit histories can slow operations. From initial setup to advanced configurations, you’ll learn specific strategies to improve Git performance with practical examples.
git lfs install
git lfs track "*.psd"
git add .gitattributes
git commit -m "Enable Git LFS for large files"
git lfs install
: Installs LFS hooks.git lfs track "*.psd"
: Tracks all .psd
files with LFS..gitattributes
: Stores tracking rules for LFS.
git clone --depth=1
--depth=1
fetches only the most recent commit, speeding up the cloning process.
git config fetch.parallel 4
git config --global gc.auto 500
Explanation: Setting a higher threshold reduces the frequency of garbage collection, ideal for large repositories.
git clone --filter=blob:none --no-checkout
--filter=blob:none
excludes file contents, downloading only the metadata. --no-checkout
delays checkout until necessary.
git config core.sparseCheckout true
echo "path/to/directory/" >> .git/info/sparse-checkout
git read-tree -mu HEAD
core.sparseCheckout true
: Enables sparse checkout.read-tree -mu HEAD
: Updates the working tree based on sparse-checkout settings.
git gc --aggressive --prune=now
--aggressive
provides a more thorough cleanup, and --prune=now
deletes unreferenced objects immediately.git repack
reduces disk usage by packing loose objects and optimizing the repository structure.
git repack -Ad
Explanation: -A
repacks all objects, while -d
removes redundant packs.
git worktree add ../feature_branch feature_branch
git status
.
git config core.preloadIndex true
GIT_TRACE=1 git status
This chapter covered strategies for improving Git performance in large repositories by managing large files, optimizing history, and using efficient storage techniques. By following these steps, large repositories become faster, easier to manage, and more efficient in both solo and team settings. Happy coding !❤️
