Running npm the first time on `aws/codebuild/standard:7.0` takes 12 seconds

[moltar]

Running npm CLI for the first time on CodeBuild takes 12s seconds. And that's in 15 GB memory, 8 vCPUs.

10.2.4

I suspect it has something to do with corepack. It silently tries to update npm or maybe apt-get; I think it has a similar behaviour.

But I tried disabling corepack via corepack disable and also setting various env options to turn off different behaviours. But nothing seems to have any effect.

Any ideas?

Shouldn't npm be pre-installed by default?

Just tried aws/codebuild/standard:6.0 and aws/codebuild/amazonlinux2-x86_64-standard:5.0 and it's the same behaviour across all images.

Also, a weird scenario, simply running apt installs, will somehow magically speed up npm run.

Is it a filesystem warm up? Is it some background job that does some optimization?
