Autocomplete when typing is really slow.

[damisparks]

Issue Type: Performance Issue

Autocomplete when typing is really slow. I have to wait for at least 5 seconds to see the suggestions.

It looks like the issue is caused by one of your installed extensions. All extensions execute together on a single nodejs process, so in order to narrow down the possible problematic extension, please try the following:

• run F1 > Help: Start Extension Bisect
• (this will restart VS Code with half of your extensions disabled)
• try to do the steps which reproduce the problem
• if the problem reproduces, click "This is bad" (this narrows down the problematic extension to the half which was enabled)
• if the problem does not reproduce, click "Good now" (this narrows down the problematic extension to the half which was disabled)
• these steps will repeat until the problematic extension is found

Thank you for providing the steps for troubleshooting this.

Here is what I got after. 👇🏾

Quick update.

• I noticed the slowness only occurs on this specific project I am working on.
• However, I tried creating a jsconfig.json file for the project according to these docs What is jsconfig.json? The slowness stops and started again this morning.
• Here is the content of the jsconfig.json 👇🏾

{
  "compilerOptions": {
    "module": "ESNext",
    "moduleResolution": "Node",
    "target": "ES2020",
    "jsx": "preserve",
    "strictFunctionTypes": true
  },
  "exclude": ["node_modules", "**/node_modules/*"]
}

I am still having the same issue 🤦🏾‍♂️

I tried something else.

• I deleted the node_modules and install it again
• it started working normally again. It is quite strange.

[jrieken]

So, the problem only occurs with specific projects and those are all JavaScript/Typescript? Is that right? Is auto-complete in other files, like CSS or HTML, acceptable fast?

To answer your question:

• Yes, the problem only occurs with this specific JavaScript project.
• Other projects are working absolutely fine

[mjbvz]

Does this reproduce in the latest VS Code insiders build with all extensions disabled?

If it does, please share a minimal project that demonstrates the issue

[damisparks]

@mjbvz
Thank you for your suggestion.

• The issue reproduces with the last VS Code insiders build with all extensions disabled.
• I created a simple node project with only express installed via npm. Everything works fine with or without the extensions disabled.

At this time, I am lost and still investigating the issue.

Nevertheless, I noticed one thing though.
For this specific project that I am having issue with, I have to reload VS code multiple times for the autocomplete to work normally.
To give more context,

• I reload and type to see what happens, if the autocomplete works as fast it should be, I continue working else I reload again.
