如何对 websockets 进行负载测试 [英] How to do load testing for websockets

问题描述

我们正在构建一个使用 websockets 的群聊功能.我们想测试我们当前的基础架构可以支持多少个连接.

We are building a group chat feature, which is using websockets. We want to test how many connections our current infrastucture can support.

基本上归结为如何模拟 websocket.

Basically it boils down to how to simulate a websocket.

推荐答案

我可以根据我最近的经验给你一个建议.您可以将基于 webkit 的 Phantom 虚拟客户端连接到您的聊天服务器并测量资源使用情况(即 CPU、内存，可能正在使用 shell 脚本或其他实用程序，或者您可以分析您的服务)

I can give you a suggestion from my recent experience. You can connect webkit based Phantom virtual clients to your chat server and measure the resource usage (i.e CPU, memory, may be using a shell script or another utility or you can profile your service )

var system = require('system');
var page = require('webpage').create();
page.viewportSize = { width: 1024, height: 768 };

page.open("<URL to chat server service>", function (status) {
    // Check for page load success
    if (status !== "success") {
        console.log("Unable to connect");
        phantom.exit();
    } else {
        console.log("Client connected  ");
        //after connecting you may extract further information, taking screenshots etc. refer the phantom.js API for further details
    }
});

您是否使用套接字 IO 之类的任何框架进行 websocket 通信?

Do you use any framework like socket IO for websocket communication ?
