Cluster & Toobusy - an awesomely scalable node setup
// Include libraries
var express = require('express');
var cluster = require('cluster');
var toobusy = require('toobusy');
if (cluster.isMaster) {
var cpus = require("os").cpus();
console.log("CPU Info:");
console.log(cpus);
for (var i = 0; i < cpus.length; i++) {
cluster.fork();
}
console.log("Running master");
} else {
// Create a new Express application
var app = express();
app.use(function(req, res, next) {
if (toobusy()) res.send(503, "Server melting, sorry :)");
else next();
});
// Add a basic route – index page
app.get('/', function (req, res) {
res.send('Hello World from the world of worker ' + cluster.worker.id + '!');
console.log("Serving from worker " + cluster.worker.id);
});
// Bind to a port
app.listen(3000);
console.log("Running worker " + cluster.worker.id);
}
