Measure, monitor, and optimize API gateway proxy latency. Understand the factors affecting response time and implement strategies to achieve sub-100ms performance.
Physical distance between client, gateway, and backend services.
Time spent on authentication, validation, and transformation.
Time waiting for backend services to process requests.
Time to establish secure connection (especially for new connections).
Maintain persistent connections to backend services to eliminate connection overhead.
Reuse TCP connections for multiple requests to reduce handshake time.
Place gateways closer to users with global edge network deployment.
Cache responses at the gateway level to serve repeated requests instantly.
Compress responses and minimize unnecessary data transfer.
Multiplex requests over single connection for better performance.
