Message payload size reduction from 1KB to 100 bytes improves throughput 5x

Large Socket.io message payloads (1KB+) increase latency under concurrent connections. Reducing payload size from 1KB to 100 bytes can boost throughput by 5x.

Minimize event payload sizes by removing unnecessary data fields and using efficient serialization. Consider Protocol Buffers or MessagePack instead of JSON to reduce size and processing overhead. Compress payloads only when benefits outweigh CPU costs. Profile serialization steps to identify optimization opportunities.
