Output Example

Wheels Application Optimization
==============================

Analyzing application...
✓ Scanned 245 files
✓ Analyzed 1,234 queries
✓ Checked 456 assets

Optimizations Applied:
---------------------

Database (4 optimizations)
  ✓ Added index on users.email
  ✓ Added composite index on orders(user_id, created_at)
  ✓ Optimized slow query in ProductModel.cfc
  ✓ Enabled query caching for static queries

Assets (3 optimizations)
  ✓ Minified 23 JavaScript files (saved 145KB)
  ✓ Optimized 15 CSS files (saved 67KB)
  ✓ Compressed 34 images (saved 2.3MB)

Caching (2 optimizations)
  ✓ Configured Redis for object caching
  ✓ Enabled page caching for static routes

Code (3 optimizations)
  ✓ Removed 12 unused functions
  ✓ Optimized application startup
  ✓ Reduced memory footprint by 15%

Performance Impact:
  - Page load time: -32% (2.4s → 1.6s)
  - Database queries: -45% (avg 23ms → 12ms)
  - Memory usage: -15% (512MB → 435MB)
  - Startup time: -20% (8s → 6.4s)

Configuration

Configure via .wheels-optimize.json:

{
  "optimize": {
    "database": {
      "autoIndex": true,
      "queryCache": true,
      "slowQueryThreshold": 100
    },
    "assets": {
      "minify": true,
      "bundle": true,
      "compress": true,
      "compressionQuality": 85
    },
    "cache": {
      "provider": "redis",
      "ttl": 3600,
      "autoEvict": true
    },
    "code": {
      "removeDeadCode": true,
      "optimizeStartup": true,
      "memoryOptimization": true
    }
  }
}

Optimization Strategies

Development Mode

Focuses on developer experience:

wheels optimize --env=development

• Faster rebuilds

• Source maps preserved

• Debug information retained

Production Mode

Maximum performance:

wheels optimize --env=production

• Aggressive minification

• Dead code elimination

• Maximum compression

Balanced Mode

Balance between size and debuggability:

wheels optimize --mode=balanced

Advanced Options

Selective Optimization

# Only database optimizations
wheels optimize --only=database

# Exclude asset optimization
wheels optimize --skip=assets

# Specific optimizations
wheels optimize --optimizations=minify,compress,index

Performance Budgets

# Set performance budgets
wheels optimize --budget-js=200kb --budget-css=50kb

# Fail if budgets exceeded
wheels optimize --strict-budgets

Integration

Build Process

{
  "scripts": {
    "build": "wheels optimize --env=production",
    "build:dev": "wheels optimize --env=development"
  }
}

CI/CD Pipeline

- name: Optimize application
  run: |
    wheels optimize --env=production
    wheels optimize --verify

Rollback

If optimizations cause issues:

# Create backup before optimizing
wheels optimize --backup

# Rollback to backup
wheels optimize --rollback

# Rollback specific optimization
wheels optimize --rollback=database

Best Practices

1. Test After Optimization: Verify functionality

2. Monitor Performance: Track real-world impact

3. Incremental Approach: Optimize gradually

4. Keep Backups: Enable rollback capability

5. Document Changes: Track what was optimized

Performance Monitoring

After optimization:

# Verify optimizations
wheels optimize --verify

# Performance benchmark
wheels optimize --benchmark

# Compare before/after
wheels optimize --compare

Common Issues

Over-optimization

• Breaking functionality

• Debugging difficulties

• Longer build times

Solutions

• Use balanced mode

• Keep source maps in development

• Test thoroughly

Use Cases

1. Pre-deployment: Optimize before production

2. Performance Issues: Fix slow applications

3. Cost Reduction: Reduce resource usage

4. User Experience: Improve load times

5. Scalability: Prepare for growth

Notes

• Always backup before optimization

• Some optimizations require restart

• Monitor application after optimization

• Optimization impact varies by application
