High Performance Git

High Performance Git explores the internal layers of Git and their performance costs, providing essential knowledge for engineers to keep Git fast as repositories and teams scale.

Git looks like a version-control tool. It is also a content-addressed database, a filesystem cache, a graph walker, and a transfer protocol.

This book is about those layers and the performance costs of each one. It starts with objects, refs, the index, and history traversal, then moves outward into packfiles, maintenance, sparse working trees, partial clone, transport, repository scale, diagnosis, configuration, and recovery.

It is written for engineers who need Git to stay fast as repositories, histories, and teams get larger: build and CI engineers, monorepo owners, developer-experience teams, and the people who wind up debugging strange Git behavior when the easy explanations stop working.
