这是一个显示如何使用 CPU 分析器的示例：

¥Here's an example showing how to use the CPU Profiler:

import { Session } from 'node:inspector/promises';
import fs from 'node:fs';
const session = new Session();
session.connect();

await session.post('Profiler.enable');
await session.post('Profiler.start');
// Invoke business logic under measurement here...

// some time later...
const { profile } = await session.post('Profiler.stop');

// Write profile to disk, upload, etc.
fs.writeFileSync('./profile.cpuprofile', JSON.stringify(profile));
