brew tap jgavris/rs-git-fsmonitor https://github.com/jgavris/rs-git-fsmonitor.git && brew install rs-git-fsmonitor

# Configure git repository to use the tool (run in desired large git repository):
git config core.fsmonitor rs-git-fsmonitor

Via Habitat

Habitat is the recommended way to install in Linux environments:

# Install and link packages
sudo hab pkg install jgavris/rs-git-fsmonitor
sudo hab pkg binlink jgavris/rs-git-fsmonitor
sudo hab pkg binlink jarvus/watchman

# Ensure service directory exists and is writable
sudo mkdir -p /hab/svc/watchman/var
sudo chmod o+rwx /hab/svc/watchman/var

# Configure git repository to use the tool (run in desired large git repository):
git config --global core.fsmonitor rs-git-fsmonitor

Purpose

Git 2.16 added support for a core.fsmonitor hook to allow an external tool to inform it which files have changed.

On repositories with many files, this can be a dramatic speedup.
