Optimise local repositories with Git Garbage Collection
TIL how to optimise local repositories with Git Garbage Collection.
git is awesome. Just do not forget that if you work a lot with
git, a lot of garbage is getting piled up in your local repository, such as file revisions and other objects. To reduce disk space and increase performance,
git provides a command to compress file revisions and remove unreachable objects:
$ git gc Counting objects: 1278, done. Delta compression using up to 8 threads. Compressing objects: 100% (1068/1068), done. Writing objects: 100% (1278/1278), done. Total 1278 (delta 234), reused 1096 (delta 102)
Is it safe to run?
git gc will only optimise your local repository. The remote repository is safe! Note that some
git commands may automatically run
Every few hundred changesets or so
git gc runs very quickly. However, every hundred changesets or so you need a deeper cleaning. This can be accomplished with the
--aggressive option. Depending on the size of your repository, this can take much more time, but provides better results.
