+---
+
+# pnpm Performance Optimization
+
+pnpm is fast by default, but these optimizations can make it even faster.
+
+## Install Optimizations
+
+### Use Frozen Lockfile
+
+Skip resolution when lockfile exists:
+
+```bash
+pnpm install --frozen-lockfile
+```
+
+This is faster because pnpm skips the resolution phase entirely.
+
+### Prefer Offline Mode
+
+Use cached packages when available:
+
+```bash
+pnpm install --prefer-offline
+```
+
+Or configure globally:
+```ini
+# .npmrc
+prefer-offline=true
+```
+
+### Skip Optional Dependencies
+
+If you don't need optional deps:
+
+```bash
+pnpm install --no-optional
+```
+
+### Skip Scripts
+
+For CI or when scripts aren't needed:
+
+```bash
+pnpm install --ignore-scripts
+```
+
+**Caution:** Some packages require postinstall scripts to work correctly.
+
+### Only Build Specific Dependencies
+
+Only run build scripts for specific packages:
+
+```ini
+# .npmrc
+onlyBuiltDependencies[]=esbuild
+onlyBuiltDependencies[]=sharp
+onlyBuiltDependencies[]=@swc/core
+```
+
+Or skip builds entirely for deps that don't need them:
+
+```json
+{
+  "pnpm": {
+    "neverBuiltDependencies": ["fsevents", "cpu-features"]
+  }
+}
+```
+
+## Store Optimizations
+
+### Side Effects Cache
+
+Cache native module build results:
+
+```ini
+# .npmrc
+side-effects-cache=true
+```
+
+This caches the results of postinstall scripts, speeding up subsequent installs.
+
+### Shared Store
+
+Use a single store for all projects (default behavior):
+
+```ini
+# .npmrc
+store-dir=~/.pnpm-store
+```
+
+Benefits:
+- Packages downloaded once for all projects
+- Hard links save disk space
+- Faster installs from cache
+
+### Store Maintenance
+
+Periodically clean unused packages:
+
+```bash
+# Remove unreferenced packages
+pnpm store prune
+
+# Check store integrity
+pnpm store status
+```
+
+## Workspace Optimizations
+
+### Parallel Execution
+
+Run workspace scripts in parallel:
+
+```bash
+pnpm -r --parallel run build
+```
+
+Control concurrency:
+```ini
+# .npmrc
+workspace-concurrency=8
+```
+
+### Stream Output
+
+See output in real-time:
+
+```bash
+pnpm -r --stream run build
+```
+
+### Filter to Changed Packages
+
+Only build what changed:
+
+```bash
+# Build packages changed since main branch
+pnpm --filter "...[origin/main]" run build
+```
+
+### Topological Order
+
+Build dependencies before dependents:
+
+```bash
+pnpm -r run build
+# Automatically runs in topological order
+```
+
+For explicit sequential builds:
+```bash
+pnpm -r --workspace-concurrency=1 run build
+```
+
+## Network Optimizations
+
+### Configure Registry
+
+Use closest/fastest registry:
+
+```ini
+# .npmrc
+registry=https://registry.npmmirror.com/
+```
+
+### HTTP Settings
+
+Tune network settings:
+
+```ini
+# .npmrc
+fetch-retries=3
+fetch-retry-mintimeout=10000
+fetch-retry-maxtimeout=60000
+network-concurrency=16
+```
+
+### Proxy Configuration
+
+```ini
+# .npmrc
+proxy=http://proxy.company.com:8080
+https-proxy=http://proxy.company.com:8080
+```
+
+## Lockfile Optimization
+
+### Single Lockfile (Monorepos)
+
+Use shared lockfile for all packages (default):
+
+```ini
+# .npmrc
+shared-workspace-lockfile=true
+```
+
+Benefits:
+- Single source of truth
+- Faster resolution
+- Consistent versions across workspace
+
+### Lockfile-only Mode
+
+Only update lockfile without installing:
+
+```bash
+pnpm install --lockfile-only
+```
+
+## Benchmarking
+
+### Compare Install Times
+
+```bash
+# Clean install
+rm -rf node_modules pnpm-lock.yaml
+time pnpm install
+
+# Cached install (with lockfile)
+rm -rf node_modules
+time pnpm install --frozen-lockfile
+
+# With store cache
+time pnpm install --frozen-lockfile --prefer-offline
+```
+
+### Profile Resolution
+
+Debug slow installs:
+
+```bash
+# Verbose logging
+pnpm install --reporter=append-only
+
+# Debug mode
+DEBUG=pnpm:* pnpm install
+```
+
+## Configuration Summary
+
+Optimized `.npmrc` for performance:
+
+```ini
+# Install behavior
+prefer-offline=true
+auto-install-peers=true
+
+# Build optimization  
+side-effects-cache=true
+# Only build what's necessary
+onlyBuiltDependencies[]=esbuild
+onlyBuiltDependencies[]=@swc/core
+
+# Network
+fetch-retries=3
+network-concurrency=16
+
+# Workspace
+workspace-concurrency=4
+```
+
