Performance Optimization System - Development Version

Hệ thống tối ưu hiệu suất cho Jankx 2.0, bao gồm asset management, Core Web Vitals monitoring và performance optimization tools.

🚧 Development Status

⚠️ Lưu ý: Performance system trong Jankx 2.0 hiện đang trong giai đoạn phát triển (Development). Một số tính năng có thể chưa hoàn thiện.

Current Status:

  • 🔄 Asset Management: Đang phát triển
  • 🔄 Core Web Vitals: Đang phát triển
  • 🔄 Performance Monitoring: Đang phát triển
  • 🔄 Optimization Tools: Đang phát triển

📚 Nội dung chính

🔄 In Development (Đang phát triển)

🎯 Mục tiêu Performance

Core Web Vitals Targets

  • LCP (Largest Contentful Paint): < 2.5s
  • FID (First Input Delay): < 100ms
  • CLS (Cumulative Layout Shift): < 0.1

Performance Metrics

  • First Paint: < 1.5s
  • Time to Interactive: < 3.5s
  • Speed Index: < 3.4s

🔧 Current Implementation

Basic Asset Management

// Hiện tại: Basic asset enqueue
add_action('wp_enqueue_scripts', function() {
    wp_enqueue_style('jankx-style', get_template_directory_uri() . '/assets/css/style.css');
    wp_enqueue_script('jankx-script', get_template_directory_uri() . '/assets/js/script.js');
});

Manual Performance Optimization

// Hiện tại: Manual optimization
add_action('wp_head', function() {
    // Critical CSS inline
    echo '<style>' . file_get_contents(get_template_directory() . '/assets/css/critical.css') . '</style>';
});

add_action('wp_footer', function() {
    // Defer non-critical CSS
    echo '<link rel="preload" href="' . get_template_directory_uri() . '/assets/css/non-critical.css" as="style" onload="this.onload=null;this.rel=\'stylesheet\'">';
});

🚀 Planned Features

Phase 1: Asset Management 🔄

  • Automatic asset optimization
  • Critical CSS generation
  • Asset bundling and minification
  • Lazy loading implementation

Phase 2: Performance Monitoring 🔄

  • Core Web Vitals monitoring
  • Performance metrics collection
  • Real-time performance dashboard
  • Performance alerts

Phase 3: Advanced Optimization 📋

  • Automatic image optimization
  • Service worker implementation
  • Advanced caching strategies
  • CDN integration

📊 Performance Monitoring

Current Monitoring (Basic)

// Basic performance monitoring
add_action('wp_footer', function() {
    if (defined('WP_DEBUG') && WP_DEBUG) {
        $loadTime = microtime(true) - $_SERVER['REQUEST_TIME_FLOAT'];
        echo "<!-- Page load time: {$loadTime}s -->";
    }
});

Planned Advanced Monitoring

// Planned: Advanced performance monitoring
class PerformanceMonitor
{
    public function trackCoreWebVitals(): void
    {
        // LCP, FID, CLS tracking
    }

    public function trackCustomMetrics(): void
    {
        // Custom performance metrics
    }

    public function generateReport(): array
    {
        // Performance report generation
    }
}

🔧 Configuration

Current Configuration (Basic)

// config/performance.php
return [
    'debug' => defined('WP_DEBUG') && WP_DEBUG,
    'minify' => !defined('WP_DEBUG') || !WP_DEBUG,
    'cache' => true,
];

Planned Configuration

// Planned: Advanced configuration
return [
    'core_web_vitals' => [
        'enabled' => true,
        'tracking' => true,
        'alerts' => true,
    ],
    'asset_optimization' => [
        'critical_css' => true,
        'lazy_loading' => true,
        'minification' => true,
        'bundling' => true,
    ],
    'caching' => [
        'page_cache' => true,
        'object_cache' => true,
        'browser_cache' => true,
    ],
];

🐛 Known Issues

Current Limitations

  1. Asset Management: Chưa có automatic optimization
  2. Performance Monitoring: Chưa có real-time monitoring
  3. Core Web Vitals: Chưa có automatic tracking
  4. Optimization Tools: Chưa có CLI tools

Workarounds

  • Sử dụng external performance tools (GTmetrix, PageSpeed Insights)
  • Manual asset optimization
  • Manual critical CSS generation
  • Manual performance monitoring
