📊 Metrics and 🎯 Goals for an HTTP Server Project

1. 🚀 Performance Metrics

• Throughput: Measure how many requests your server can handle per second.
• Latency: Measure response times (average and p99 latency) under varying loads.
• Concurrency: Test how the server performs with 10, 100, or 1,000 concurrent connections.
• CPU/Memory Usage: Profile the server under load to ensure efficient resource usage.

2. 🛠️ Features and Extensibility

• Static File Serving:
  • Serve files efficiently with support for partial requests (HTTP Range headers).
• Logging Support:
  • Allow users to keep track of errors through logging.
• Customizable Error Handling:
  • Add meaningful HTTP error codes and allow users to define error pages.

3. 📚 HTTP Compliance

• HTTP 1.1 Support:
  • Include persistent connections with keep-alive headers.
• Standards Adherence:
  • Properly handle request/response headers, content encoding, and status codes.
• Content Negotiation:
  • Respond based on Accept headers (e.g., Image or HTML).

4. 📈 Scalability and Concurrency

• Asynchronous I/O:
• Thread Pooling:
• Load Testing:

5. 🔧 Advanced Features

• Caching:
  • Implement in-memory caching for frequently requested resources.
  • Support ETag or Last-Modified headers.
• Rate Limiting:
  • Prevent abuse by limiting the number of requests from a single IP.
• Logging:
  • Log requests and generate usage analytics (e.g., popular endpoints, error rates).

🎯 Advanced Goals

1. Set Performance Targets:
   • Handle 3k RPS (requests per second) with less than a 1% error rate.
2. Compliance:
   • Pass an HTTP compliance suite like h2spec.
