bun install is slower than npm ci

[beeb]

I normally use npm ci to install dependencies into the build step of a Dockerfile.

With my project, this takes about 4.4s 2.7s to 3.2s for the install step, on my machine.

I tried to switch to bun.
Generated a bun.lockb file beforehand and copying it inside the container.
Using the following command instead: bun i --ignore-scripts --frozen-lockfile, it takes 22.7s 3.3s to 5s.

With --no-verify the results are almost identical.

How can I speed this up?

EDIT: repeated on Ubuntu (not using Windows/WSL2)

Windows?

Docker Desktop is running on Windows but it's using WSL2 under the hood I believe.

Repeated the experiment on my Ubuntu laptop (multiple runs in succession without docker caching for each):

npm ci: 2.7s to 3.2s
bun install (with command from the post above): 3.3s to 5s

I'm glad it's nowhere near as bad, but still is there room for improvement, as I imagine this will become even more apparent in CI?

Could you share a package.json file or something? At least create a reproducible example for us.

@melroy89 will start working on creating a repro using a similar setup to what I have here (private CodeArtifact registry for some dependencies)
