我的聊天工作在24个线程（2x 6核X5650 @ 2.67GHz）...如果有大约1000个连接CPU使用率（在每个线程上）增长到80-100％....我认为有些东西是我的代码错了...节点不应该只用1000个连接生成这样的负载。你能不能给我一些关于在哪里看看的想法
我的代码：
express = require('express')
http = require('http');

port = 55678;
userCount = 0;

redis = require("socket.io/node_modules/redis"),
pub = redis.createClient(),
sub = redis.createClient(),
client = redis.createClient(),
counter = redis.createClient();
counter.set('count',0);
client.set('searching',0);
client.del('freeusers');
if (cluster.isMaster) {
for (var i = 0; i < numCPUs; i++) {
cluster.fork();
}
}
