[Bug] performance issue with yarn node

[Ayc0]

• I'd be willing to implement a fix

Describe the bug

Since I switched to yarn berry, I noticed that we had a noticeable slowdown when running yarn exec commands:

For instance here is a comparison between yarn node and node -r for logging "red" in red with chalk:

(I have a lot of modules in my package but even with an empty package.json, we have the same issue, see reproduction section)

Yarn node	node -r

We can notice that there is a huge slowdown when running through yarn

To Reproduce

Reproduction

mkdir test
cd test
yarn init -y
yarn set version berry
time yarn node -e "console.log('red')"
time node -r ./.pnp.js -e "console.log('red')"

Screenshots

Node -r	Yarn node

Environment if relevant (please complete the following information):

• OS: macOS 10.15.7
• Node version: Both v15.14.0 and v12.16.1
• Yarn version: both 2.4.0-git.20210210.hash-cb8c8d68 and 2.4.1

Master already contains various improvements. Likely duplicate of #2560 (comment)

[Ayc0]

Thanks, I'll try the new master!

[Ayc0]

I don't think master improved the situation that much:

yarn node -e "console.log('a')" still takes more than 1s:

and I'm running yarn 3-rc2

I'll close this as a duplicate of #2575 since yarn node goes through the same process as running scripts
