test/parallel/test-cli-node-options.js

If all we're doing with -e is console.log() perhaps consider using -p instead?

refack · 2017-07-12T17:11:05Z

-p 5.17s, 5.16s, 5.11s
-e 4.92s, 4.78s, 4.76

(faster by 5% with p = 2.3E-05)
Going back 🤷‍♂️

This is mainly to avoid timing out, currently on pi1-raspbian-wheezy the joined file can take > 40s
