集群的NodeJS高内存使用率

Question

我用快递静态插件，Windows 2008的64位，8G内存，万兆网，节点-6.9.x 64位

var cluster = require("cluster"); 
var http = require("http"); 
var express = require("express"); 
if(cluster.isMaster()){ 
    for (var i = 0; i < 4; i++) 
    cluster.fork(); 
}else{ 
    var express = require("express"); 
    var app = express(); 
    var http = require("http"); 
    app.use(express.static("")); 
    http.createServer(app).listen(8080); 
} 

记忆增长速度非常快，从1GB到8G的约五minutes.at这次约1500 connections.outgoing带宽300MB /万兆，约150MB，主进程30MB每一个工作进程。

内存所使用的是谁？大约15分钟，工作人员进程崩溃。

我尝试HTTP服务器模块（NPM安装HTTP服务器），相同的结果。

我使用AB测试我的笔记本电脑10秒测试代码（带有一点点的变化），效果很好。 变化是cluster.isMaster和app.use(express.static("/"));

var cluster = require("cluster"); 
var http = require("http"); 
var express = require("express"); 
if(cluster.isMaster){ 
    for (var i = 0; i < 4; i++) 
    cluster.fork(); 
}else{ 
    var express = require("express"); 
    var app = express(); 
    var http = require("http"); 
    app.use(express.static("/")); 
    http.createServer(app).listen(8080); 
} 

结果是：
