[BUG] npm ls is still slow

[Rudxain]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

npm/npm#6507

• On an Dell Inspiron 15R, with its HDD replaced by an SSD, running Debian 13 (Node LTS), it takes ~1.2s
• On a Samsung Galaxy A31, from Termux repos (Node latest), it takes ~3s

It's slow, both with and without -g flag. Even on directories that contain no package.json

Expected Behavior

It should be sub ~500ms

Steps To Reproduce

1. On Debian or Termux
2. Run time npm list (-g optional)
3. See timings

Environment

• npm: 10.9.0
• Node.js: v20.17.0
• OS Name: Debian 13 "Trixie"
• System Model Name: Inspiron 5521
• npm config:

I'm using npm 11.0.0 and it works fine for me (output: [email protected] D:\Websites\HTML-CSS-OLD -- [email protected]). The results come in in about 3 secs.

You have the early-release version, as I can tell. Try the 22.x (LTS) one, it should work there.

Note

Before I reply to comments, I want to apologize to maintainers for sending too much Termux "benchmarks". I'm aware I should report those issues here.

I'll send more Debian benchmarks in some minutes.

And I'm aware that the same reasoning applies to Debian, as I've installed Node and NPM from deb repos, not upstream/mainline.

Try the 22.x (LTS)

nodejs-lts (v22.12.0) is worse (I forgot to update NPM after installing LTS 🤦):

That's odd 😕

@Rudxain i would avoid using termux with npm, because termux sets PREFIX, which npm also uses.
