k6 压测脚本与性能指标分析

k6 压测脚本与性能指标分析脚本示例 `script.js`import http from 'k6/http';

import { sleep } from 'k6';

export const options = {

vus: 50,

duration: '30s',

thresholds: {

http_req_duration: ['p(95)<800'],

http_req_failed: ['rate<0.01']

}

};

export default function () {

const res = http.get('https://example.com/api/items');

sleep(0.5);

}

运行k6 run script.js

分析要点关注 `p(95)`、错误率与吞吐根据瓶颈调整并发、资源与缓存策略总结k6 提供简洁的压测模型与阈值控制，适合开发与 CI 环境的稳定验证。
