If everything wasn't NIO, Node.js would perform terribly. In fact it's not recommended for users of Node.js to do anything CPU heavy inside a Node.js process as that will destroy overall server perf. You have to offload that work to a WebWorker (and setup some callbacks). If you're trying to build a Node.js app that takes advantage of multiple cores you need to create as many Node.js processes as you have cores. Communicating across processes for even something as simple as a counter will incur more callback complexity as well as overhead (or you can avoid IPC and use an in-memory store like MongoDB, and just pay the overhead of communicating to the DB). So while I find Node.js intriguing for simple projects, I'm looking forward to seeing how that community builds around these issues in larger software endeavors. Clojure, because of the JVM, doesn't tie your hands this way. If you want to do everything evented go ahead. Do everything with threads? Go ahead. Want to mix the two designs together like Aleph? Sure. All while not losing the elegant brevity of a Node.js app. I like JavaScript, and I like Node.js. But I think Clojure opens up some new avenues to explore when building web applications. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
