@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);
});
}支持四种任务类型：
addAsync(title, async () => void)添加async function，需要返回 PromiseaddCallback(title, (callback) => void)添加异步回调函数addSync(title, () => void)添加阻塞函数addSyncFaster(title, (count) => void)添加阻塞函数，函数内部通过 for 循环运算
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
