Linking dependencies takes an extreme amount of time for basic yarn add operations in Yarn 1.13.0

Bug.

What is the current behavior?

yarn add with any package takes over 5 minutes to "Link dependencies" in a fairly standard Angular project.

yarn add codelyzer --dev

Final time taken:

If the current behavior is a bug, please provide the steps to reproduce.

With the following package.json file, ~52,000 entities need to be linked, in a process that can take anywhere from 300 seconds to 600 seconds. I am not currently utilising offline cache, nor should I have to.

What is the expected behavior?

I would expect this level of sluggishness when installing all packages for the first time, but not for a minor yarn add operation.

Please mention your node.js, yarn and operating system version.

macOS 10.14.3
node 11.10.1
yarn 1.13.0

Do you have any anti-malware (including Windows Defender) installed/enabled?

[lukeify]

Nope, this is effectively a stock install on macOS
