@leizm/benchmark v2.0.1

@leizm/benchmark

简单性能测试框架，支持预热和多进程执行（针对异步任务）。

安装

npm i @leizm/benchmark -S

用法

import Benchmark from "@leizm/benchmark";

const b = new Benchmark({ title: "Benchmark Example" });
b.addAsync("async task", async () => await sleep(0))
  .addCallback("callback task", done => sleep(0).then(done))
  .addSync("sync task", () => 1 + 1)
  .addSyncFaster("sync faster task", count => {
    for (let i = 0; i < count; i++) {
      // ... 针对性能损坏极小的同步任务，使用 for 来循环 count 次
    }
  })
  .runAndPrint();

function sleep(ms: number): Promise<number> {
  return new Promise(resolve => {
    setTimeout(resolve, ms);
  });
}

注意：addAsync() 和 addCallback() 中的任务必须是真正的异步函数，否则可能造成进程卡死

选项

export interface Options {
  /** 标题 */
  title: string;
  /** 每个任务执行时长（秒） */
  seconds: number;
  /** 并发数量（异步任务时有效） */
  concurrent: number;
  /** 每个任务间隔（秒） */
  delay: number;
  /** 预热时间（秒） */
  preheat: number;
  /** 是否开启多进程，默认不开启 */
  clusterMode: boolean;
  /** 子进程数量，默认为CPU总数 */
  clusterCount: number;
}
