Visual Studio Code Intellisense is very slow - Is there anything I can do?

问题


I'm using VS Code and it's wonderful is all areas but code completion, where it is usually just too slow to be of any use. This example shows how long intellisense took to to find a local variable, and this is only after it was prompted to do so after I hit ctrl+enter.

I've not been able to find a solution to this as of yet, so I am here to ask if anyone else has had a similar issue and ask how they have overcome it.


回答1:


It turned out it was a particular VS Code extension for me.
Angular Language Service. Disabling this made it lightning quick.

Try this to see if it is a particular extension.

  • Open Command Palette (Ctrl+Shift+P)
  • Type in "Disable all installed extensions"
  • Enable them one by one or in groups and test the intellisense speed

The problem might be with wrong setting configuration.
You might want to make sure these setting are on:

Controls if suggestions should automatically show up while typing

"editor.quickSuggestions": {
  "other": true,
  "comments": false,
  "strings": false
},

Controls the delay in ms after which quick suggestions will show up

"editor.quickSuggestionsDelay": 10,

My answer's for c++ but still kinda related.

I'm using the C/C++ extension from Microsoft, and when I switched its Intelli Sense Engine setting from Default, with "context-aware results", to Tag Parser, with "'fuzzy' results that are not context-aware", it immediately started showing IntelliSense options instead of delaying for 5+ seconds.

So maybe check the particular options of your language's or environment's extension(s).
