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

My project needs around 2000 packages. When running "npm install" it starts out by opening 2000 connections and then when all the connections are open it downloads 1 package on each connection.

Is this intended?, because it causes a quite high load on our package proxy. Is there a way to limit the number of connections?

With npm 9.9 it only uses 18/20 connections.

Expected Behavior

"npm install" only opens a few connetions to the package server.

Steps To Reproduce

1. Clear cache
2. npm install or npm ci
