Official website: https://k6.io/

Using this tool is very simple, the specified number of people / time / script can work The problem will be in how the script is written. (The number of people is related to the memory, depending on the machine of the tool)

Here is a simple scripting

• Create a test.js
• Enter the following content and then archive
  
  

    import http from "k6/http";
    import { check } from "k6";
    
    export default function() {
      check(http.get("www.targetweb.com"), {
        "status is 200": (r) => r.status == 200,
      });
    }

• Use the following instructions to operate the tool
