Poor performance on some projects #389

Description

@jrparish

I'm opening a new issue since the other (#243) is closed and might not have visibility, but please close if not appropriate.

We are trying to use typescript-eslint on a pretty large project with 1000+ files. The CLI is very slow (see stats below), which I am able to live with, but since starting to use this plugin all our developers have been experiencing system lockups when running VSCode with the eslint plugin.

Additional info from my comment on the closed issue (#243 (comment)) -

CLI stats:

tslint with project - 20s
eslint with project - 96s
eslint without project - 57s

How many files are there?
1000+

Are you linting a multi tsconfig repo?
No

What rules are you using?
recommended + airbnb + prettier

Are you running eslint in watch mode? Via your ide? Via CLI on your entire repo?

  • CLI, non-watch
  • VSCode
