[Question] Slow performance issue

[Shuunen]

Hi there :)

Thanks for your project, I really like the meta plugin aspect, the only thing is I'm surprised to see so much delay to process a single file,

I made a super simple TS project that use hardcore & typescript : https://github.com/Shuunen/minimal-ts-hardcore

Is it normal to take 7 seconds for a single file ?

Am I missing something ?

Thanks

I also encountered slow performance, after disabling some rule it improves a lot

[Shuunen]

@qweered What's the performance you have after disabling these rules?

Its like down from 12 seconds to 5, I disable some typescript eslint rule, cannot remember more

You can use TIMING=1 to see slow rules:

❯ TIMING=1 npx eslint main.ts

Yes I used this and file types overrides to improve performance, but still I'd like to improve the time spent, I will try to fork this repo to try to embed less plugins, see if it does the same as disabling these slow rules
