    proxy_settings = {
 ‘rotation_interval‘: ‘300 seconds‘,
 ‘concurrent_connections‘: 5,
 ‘geo_targeting‘: [‘US‘, ‘EU‘, ‘ASIA‘],
 ‘session_persistence‘: True
}

  2. Performance Metrics:

Proxy Type Success Rate Average Speed Cost/Month
Residential 95% 1.2s $200-500
Datacenter 85% 0.8s $50-150
Mixed Pool 90% 1.s $150-300
