node.js – 在AWS节点上,socketcluster无法连接超过1000个连接

我正在运行一个简单的socketcluster node.js服务器并从node.js websocket客户端连接到它.

通过在我的本地Ubuntu14.04上运行服务器,我可以将超过10,000个客户端连接到服务器.但是在AWS EC2(c3-largE)ubuntu14.04实例上,相同的代码仅连接少于1000个连接.

修改了etc / security / limits.conf,并在EC2实例上将“soft nofile”和“hard nofile”的限制设置为65535.

建议Node.js maxing out at 1000 concurrent connections的Posix软限制没有帮助.

其他sysctl参数在我的本地ubuntu和EC2实例之间没有太大差异.

延迟可能不是问题,因为我试图从多个客户端计算机连接到服务器仍然保持连接数量< 1000. 是否存在可能影响性能的AWS环境变量？
进出EC2的消息数量是否有限制？

var posix = require('posix');
posix.setrlimit('nofile',{soft:10000});

var SocketCluster = require('socketcluster').socketCluster;
var numcpus = require('os').cpus().length;
var numWorkers = numcpus;

var start = Date.Now();
console.log("..... StarTing Server....");

process.on('uncaughtException',function (err) {
    console.log("***** SEVERE ERROR OCCURED!!! *****");
    console.log(err);
});

var socketCluster = new SocketCluster({
  balancers: 1,workers: numWorkers,stores: 1,port: 7000,appName: 'mysimapp',workerController: __dirname + '/sim_server.js',addressSocketLimit: 0,socketEventLimit: 100,rebootWorkerOnCrash: true,usesmartBalancing: true
});
