Optimizations for Low Latency
Low latency is critical for real-time communication applications like Discord:
- Proximity Routing: Connects users to nearby servers to reduce network latency.
- Global CDN: Caches static content closer to users for faster delivery.
- VoIP Optimization: Uses WebRTC and Opus codec for low-latency voice communication.
- WebSocket Protocol: Enables real-time, bidirectional communication with minimal overhead.
- Connection Resilience: Handles network disruptions and packet loss effectively.
- Server Load Balancing: Distributes traffic evenly across servers to prevent overloads.
- Asynchronous Processing: Handles requests concurrently without blocking to reduce latency.
- Client-Side Optimization: Implements efficient algorithms and minimizes network requests for faster interactions.
