# Optimize and Accelerate Git Operations

When working with large repositories, Git operations such as `status` and `clone` can become bottlenecks due to heavy filesystem interaction. The following configurations improve performance by reducing unnecessary work and enabling parallelism.

## Optimizing `git status` with Untracked Cache

### Overview

By default, `git status` scans the working directory to identify untracked files. In large repositories with many directories, this can result in significant overhead. Enabling `core.untrackedCache` allows Git to cache directory metadata and skip redundant directory scans when contents have not changed.

```bash
git config --global core.untrackedCache true
```

### Benefits

- **Faster** `git status` **execution** by avoiding repeated directory traversal
- **Reduced filesystem I/O**, especially in repositories with many untracked files
- **Improved developer responsiveness** in large working trees

This optimization is particularly effective in environments where repositories contain large numbers of generated or transient files.

## Optimizing Clone and Checkout with Parallel Workers

### Overview

Operations such as `git clone`, `git checkout`, `git switch`, and `git reset` require populating the working directory with files. This involves decompressing objects and writing them to disk. The `checkout.workers` setting enables Git to perform these tasks in parallel using multiple worker processes.

```bash
git config --global checkout.workers 32
```

### Benefits

- **Enhanced performance on VAST clusters**, leveraging the platform’s high-throughput and parallel access capabilities to accelerate large-scale clone and checkout operations
- **Accelerated clone and checkout operations** through parallel file processing
- **Better utilization of multi-core systems**
- **Reduced time to usable working directory after clone or branch switch**

Parallel checkout is especially impactful in large repositories with many files, where single-threaded operations become a limiting factor.

## Recommended Usage

The settings described above are recommended for all VAST-powered development environments - these optimizations provide immediate and measurable improvements in day-to-day Git workflows.
