Мое приложение node.js использует express, socket.io и общается с mongodb через mongoose.Все это работает нормально с низким использованием процессора.Когда я заставил приложение работать с кластером, оно работает нормально, но загрузка процессора действительно очень высока.Вот что я делаю.
var settings = require("./settings"),
cluster = require('cluster');
cluster('./server')
.use(cluster.logger('logs'))
.use(cluster.stats())
.use(cluster.pidfiles('pids'))
.use(cluster.cli())
.use(cluster.repl(8888))
.listen(7777);
Когда я проверяю master.log, я вижу
[Fri, 21 Oct 2011 02:59:51 GMT] INFO master started

В works.access.log я вижу все сообщения консоли, сокет.io logs etc ...
В works.error.log я вижу следующие сообщения об ошибках, похоже, что-то не так ...
node.js:134
