Description of the problem

There is an open issue regarding --enable-source-maps slowing down the performance with large bundles #41541

This can cause CPU Utilisation bumps or memory bumps if used in larger applications right now. I believe, we should mention this as a warning in documentation of --enable-source-maps because there isn't visibility on that issue apart from the particular github issue itself and it can cause some failures in production applications (it did for us because of CPU utilisation bumps)

Source map documentation: https://nodejs.org/api/cli.html#--enable-source-maps

I'll be happy to contribute if you all agree with this.

Thanks for all the work on nodejs 🎉

Go for it! A rule of thumb is that you never have to ask permission for improving the docs because we can always do better – and we can discuss the specific details on the PR review, which tends to be more productive discussion than an issue thread for this kind of things.
