very slow

[zsytssk]

very slow sometime. It even cant work in some project but the origin Tslint extension work normal.

Same issue here. Never had issue before the switch.

Please provide more info about which version of VS Code you are on, your project setup, which other extensions you have installed, and what is slow

What is slow is the auto-fix on save functionality, which was almost instant with the old extension, and now takes 4-5 seconds

[oneillsp96]

After disabling auto-save, the plugin is still unusably slow, errs out constantly, and causes me to have to restart Code every 10 minutes. Decision now is ESLint with Typescript config, or back to the deprecated TSLint extension

[squidfunk]

Same here. Unusably slow. Large files take ages to update, leading to race conditions with auto-fix on save where a change was made, the file is saved and TSLint having not caught up breaks the code.

[jesnil01]

Same issue here. It's so slow I can't believe it.

[the-ult]

Same here. Seems to be needing a lot of resources.

Especially slow while running/watching ng serve app

Today, the RC for TypeScript 3.5 was released talking about speed improvements in regard to a regression introduced in 3.4:

Unfortunately, as part of a bug fix in TypeScript 3.4 we accidentally introduced a regression that could lead to an explosion in how much work the type-checker did, and in turn, type-checking time.

As VSCode currently uses 3.4 and this extension makes heavy use of the TypeScript language server, it would explain the slowness. If this is true, we should see improvements with the next VSCode TypeScript dependency upgrade.

Does this reproduce in the latest VS Code insiders build?

[TheKrisSodroski]

Having the same issue with this. Very slow, that everything turns to a crawl. Sometimes, when I save, it doesn't recognize the changes fast enough and mangles the entire page.

Disabling the plugin resolves it.

Closing as TSLint has been deprecated in favor of ESLint and this extension is no longer being maintained

Please look into migrating to use ESLint and the ESLint VS Code extension
