How to improve ESLint performance.

[christopher-buss]

I use cspell with eslint as I have a custom eslint config that I can install once, and have an easily reproducible tool for all my linting needs. The problem currently is that the cspell plugin takes roughly 1/3 of the entire ESLint time. I understand the issue with async rules and hope this can be fixed, but for now, I'm curious about how best to approach this.

I was thinking I could disable eslint in-editor, and then only use it in git hooks/CI to minimise the cost of the plugin, but I still want spellchecking. From what I can tell, there's no way to get the VSCode extension to 1:1 mimic what ESLint can see - if I could, I could just run the extension on top and then use this as the async plugin.

Beyond this, are there any "best practices"/"performance guides" for setting up cspell correctly to get the most out of this plugin? E.g. disabling certain parts in CI only!
