如何有效的进行性能测试？

如何有效的进行性能测试？如何有效的进行性能测试？如何有效的进行性能测试？

一般可以用各种测试框架。比如web性能可以用jmeter等工具

有很多性能测试工具，参考：http://www.cnblogs.com/EthanCai/archive/2014/05/11/3721656.html

整个系统的性能需要至少各个模快性能达标啊。

我之前是用jmeter，最近在用另一个工具叫k6 https://k6.io/docs/，

先写个JavaScript脚本：

import http from 'k6/http';
import { sleep } from 'k6';

export default function () {
  http.get('http://test.k6.io');
  sleep(1);
}

然后进行以下的命令：

k6 run script.js

可以获得以下测试结果：

我一般是按照http_reqs来判断接口的性能
