NodeJS Source Maps Performance Test

This is a minimal example to reproduce the issue --enable-source-maps is unnecessarily slow with large source files in a close to real world scenario.

Prerequisites

• Node Version v16.13.2 (should also work with any other version that has --enable-source-maps)
• Yarn

Steps to reproduce

• Run yarn install
• Run yarn build
• Run yarn start-bundle
• In a new terminal run yarn artillery

Instead of yarn start-bundle there are also yarn start-without-source-maps, yarn start-unbundled and yarn start-bundle-with-source-map-support. Just run artillery against the different versions to see the differences in performance.

Artillery is set to do 20 req/sec for 1 minute. This should show the effect, however for really fast machines the arrivalRate of the load phase in artillery.yaml could be slightly increased.
