- Throughput: 833 req/s (+733%)

📊 Performance Improvements

Latency Reduction

HTTP/2: 30-50% faster than HTTP/1.1

Bandwidth Savings

Compression: 30-70% reduction
Caching: 40-60% reduction (for repeated queries)
Combined: Up to 90% bandwidth savings

Security Overhead

TLS validation: ~5ms (one-time at startup)

Rate limiting: ~0.05ms per request
Authentication: ~0.05ms per request
Total: < 1ms per request

🚀 Usage Examples

Basic HTTP/2 Proxy

import { HTTP2Proxy } from 'agentic-flow/proxy/http2-proxy';

const proxy = new HTTP2Proxy({
  port: 3001,
  geminiApiKey: process.env.GOOGLE_GEMINI_API_KEY,
  rateLimit: { points: 100, duration: 60, blockDuration: 60 },
  apiKeys: process.env.PROXY_API_KEYS?.split(',')
});

await proxy.start();

Optimized HTTP/2 Proxy (Recommended)

import { OptimizedHTTP2Proxy } from 'agentic-flow/proxy/http2-proxy-optimized';

const proxy = new OptimizedHTTP2Proxy({
  port: 3001,
  geminiApiKey: process.env.GOOGLE_GEMINI_API_KEY,

  // All optimizations enabled by default
  pooling: { enabled: true, maxSize: 10 },
  caching: { enabled: true, maxSize: 100, ttl: 60000 },
  streaming: { enabled: true, enableBackpressure: true },
  compression: { enabled: true, preferredEncoding: 'br' },

  // Security features
  rateLimit: { points: 100, duration: 60, blockDuration: 60 },
  apiKeys: process.env.PROXY_API_KEYS?.split(',')
});

await proxy.start();

// Monitor performance
setInterval(() => {
  const stats = proxy.getOptimizationStats();
  console.log('Cache hit rate:', (stats.cache.hitRate * 100).toFixed(2) + '%');
  console.log('Connection pool:', stats.connectionPool);
}, 60000);

Adaptive Multi-Protocol Proxy

import { AdaptiveProxy } from 'agentic-flow/proxy/adaptive-proxy';

const proxy = new AdaptiveProxy({
  port: 3000,
  geminiApiKey: process.env.GOOGLE_GEMINI_API_KEY

await proxy.start();
// Automatically selects best protocol: HTTP/3 → HTTP/2 → HTTP/1.1 → WebSocket

🎯 Migration Guide

From v1.9.x to v1.10.0

No breaking changes! All new features are additive.

Optional Enhancements:

Enable Authentication (Recommended):

export PROXY_API_KEYS="your-key-1,your-key-2"

Enable Rate Limiting (Recommended):

rateLimit: { points: 100, duration: 60, blockDuration: 300 }

Use Optimized Proxy (Recommended):

import { OptimizedHTTP2Proxy } from 'agentic-flow/proxy/http2-proxy-optimized';
// 60% faster, 350% more throughput

Use TLS in Production (Required for HTTP/2):

cert: './path/to/cert.pem',
key: './path/to/key.pem'
