1000个连接上100%的CPU使用率-Node.js、socket.io、集群和Redis。。。

我的聊天可以在24个线程上工作（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）将增长到80-100%。。。。我认为我的代码有问题。。。节点不应仅使用1000个连接生成此类负载。你能告诉我去哪里找吗

我的代码：

express     =   require('express')
http        =   require('http');
cluster     =   require("cluster");
numCPUs     =   require("os").cpus().length,
port        =   55678;
userCount   =   0;
interv      =   false;

RedisStore  =   require("socket.io/lib/stores/redis"),
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();
    }
}
