Hi hd nguyen, Thank you for the reply.
Yes, I have tried cluster-worker message sending. There are 3 issues block me from using that built-in mechanism: 1. the app I'm working on is talking in raw buffer. but when sending buffer in node's built-in cluster, it actually transmit the SlowBuffer instance, which is 8k in fixed length. That means even sending 1 byte, the actually data transition needs be 16k (8k workerA->master, 8k master-> workerB). That is a huge waste. 2. the mechanism I'm looking for is a peer-to-peer implementation. the built-in cluster is a server-route implementation, which doubles the data cost of communication, another waste. 3. I can't find an easy way to pipe a stream to a process. Am I missing something?
