Choose your fighter: benchmarking 5 WebSocket servers for Node.js—Martian Chronicles, Evil Martians’ team blog
A deep dive into benchmarking five Node.js WebSocket servers: default Socket.io, Socket.io with Connection State Recovery, uWebSockets.js, AnyCable OSS, and AnyCable Pro. The post documents two major measurement traps: a saturated single-process load generator that inflated AnyCable's p99 latency from 11ms to 234ms, and a real throughput gap between AnyCable and uWS that turned out to be genuine. Key methodology lessons include running the load generator co-located with servers, sharding clients across multiple processes to avoid event loop saturation, equalizing reconnect backoff windows across libraries, and always validating surprising results with a second independent measurement. Final results show all five servers within a few milliseconds at 10K subscribers, but AnyCable leads on 100% message delivery under network drops, deploy-time reconnect storms, and broadcast throughput at scale, while uWS is lightest per connection and Socket.io caps around 120K connections per node.
