 In some cases, the approaches above might not give you enough insight to understand why TypeScript feels slow.
 TypeScript 4.1 and higher provides a `--generateTrace` option that can give you a sense of the work the compiler is spending time on.
-`--generateTrace` will create an output file that can be analyzed within Edge or Chrome.
+`--generateTrace` will create an output file that can be analyzed by the `@typescript/analyze-trace` utility, or within Edge or Chrome.
 
 Ideally, TypeScript will be able to compile your project without any errors, though it's not a strict requirement for tracing.

 Once you're ready to get a trace, you can run TypeScript with the `--generateTrace` flag.
 
 ```
 tsc -p ./some/project/src/tsconfig.json --generateTrace tracing_output_folder
 ```
 
+In some cases, you can also take a trace from your editor. In Visual Studio Code, that can be toggled by setting `TypeScript > Tsserver: Enable Tracing` in the UI or adding the following JSON setting:

+```json5
+"typescript.tsserver.enableTracing": true,

 To quickly list performance hot-spots, you can install and run [@typescript/analyze-trace](https://www.npmjs.com/package/@typescript/analyze-trace) from npm.
