NodeJSのWriteStreamで、細かいチャンク(というか空)を大量に書き込む前後で、rssとheapTotalの差が36MBから2.5GBに広がる話。

実行例

$ uname -a
Linux docker-desktop 5.15.133.1-microsoft-standard-WSL2 #1 SMP Thu Oct 5 21:02:42 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
$ node --version
v20.14.0
$ node mem.js
before write: rss: 40.05MB, heapTotal: 4.20MB, heapUsed: 3.53MB, external: 1.33MB
writing 0: rss: 42.77MB, heapTotal: 4.45MB, heapUsed: 3.87MB, external: 1.45MB

SpaceMouseを押すと青く光って音がなるやつ。要WebHID=Chromeのみ。
<ol>
<li>音声ファイルを選ぶ: <input type="file"></li>

<li>押すと光って音がなる(Windowsとかだと Stop 3DxWare してからやるといい感じ)</li>
</ol>

const file = target.files[0];
audioUrl = file ? URL.createObjectURL(file) : undefined;
