Reducing Bandwidth with Message Compression
Cut WebSocket bandwidth using the permessage-deflate extension and smart payload design, and understand its CPU/memory trade-offs.
Bandwidth Is a Bottleneck
Real-time apps can push thousands of frames per second. On mobile and high-fan-out systems, raw bytes on the wire become a real cost in latency, data charges, and egress bills.
The permessage-deflate Extension
WebSocket defines an extension, permessage-deflate, that compresses each message with DEFLATE (the same algorithm as gzip) before it is sent and decompresses it on arrival.
