Auto imports (`getExportInfoMap`) extremely slow

[moataz9]

Issue Type: Performance Issue

trying to use ctrl + space
loading... for a period of time
when I disabled it from builtin extensions
the list is shown as expected

please vs-code team solve that problem because that builtin extension is so essential for us as a web developer
best regards
thanks.

/needsMoreInfo

Is it reproducible with all extensions disabled?
You can try this with F1 and >Developer: Reload Window With Extensions Disabled

Is this problem consistent across different projects?

[vscode-triage-bot]

Thanks for creating this issue! We figured it's missing some basic information or in some other way doesn't follow our issue reporting guidelines. Please take the time to review these and update the issue.

Happy Coding!

[moataz9]

This problem appears when working with node projects

[moataz9]

it's taking a period of time to show suggestions list

[moataz9]

[moataz9]

[moataz9]

when I disable that built-in Extention, VS Code works normally in the task manager.

[ullaskunder3]

@moataz9 Exactly I'm facing the same problem... : (

• It happens when I work with Node_modules backend project
• And It work fine for normal JavaScript files with no node packages

[moataz9]

yes that's it

[mjbvz]

Please share an example project that demonstrates the issue

[moataz9]

When I work on a small node project (using less than 4 packages) the suggestions list shown up normally. when I add more packages to use in that project, it leads the suggestions list doesn't appear normally (loading ... for a long period sometimes it take 2 min to show up and VS code in the task manager take more than normally in CPU measure as I mentioned previously )

here are the packages I use in my project

{
"dependencies": {
    "bcryptjs": "^2.4.3",
    "cors": "^2.8.5",
    "dotenv": "^10.0.0",
    "express": "^4.17.1",
    "express-async-errors": "^3.1.1",
    "express-rate-limit": "^5.3.0",
    "helmet": "^4.6.0",
    "http-status-codes": "^2.1.4",
    "joi": "^17.4.0",
    "jsonwebtoken": "^8.5.1",
    "mongoose": "^5.13.2",
    "rate-limiter": "^0.2.0",
    "swagger-ui-express": "^4.1.6",
    "xss-clean": "^0.1.1",
    "yamljs": "^0.3.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.9"
  }
}

[ullaskunder3]

@moataz9 hyy reinstalled nodejs and vs code worked

• Uninstall vs code from control panel
• delete the hidden save data from
• %UserFolder%.vscode.
• %UserFolder%\AppData\Roaming\Code
• reinstall vs code

[moataz9]

@ullaskunder3 it doesn't really work for me

[mjbvz]

@moataz9 How do I reproduce this issue using that project?
