intellisense and code navigation gets very slow

[consititine]

macOS High Sierra
vscode 1.31.1
when i use code navigation ,it takes about half minute to get the target function,which is too slow for me. I have uninstalled all the extentions but it seems doesn't work.
The feature works well in small project but slow in big project.Hoeever ,it works well too in my colleagues's mac。
Here is my setting.json:
{
"go.gopath": "/Users/yunzhanghu196/Desktop/workspace",
"window.zoomLevel": 1,
"files.autoSave": "afterDelay",
"workbench.colorTheme": "One Dark Pro Vivid",
"go.inferGopath": true,
"editor.formatOnPaste": true,
"editor.formatOnSave": true,
"editor.formatOnType": true,
"go.formatTool": "gofmt",
"go.useCodeSnippetsOnFunctionSuggest": true,
"typescript.useCodeSnippetsOnMethodSuggest": true,
"go.useCodeSnippetsOnFunctionSuggestWithoutType": true,
"go.autocompleteUnimportedPackages": true,
}
I would be grateful if any one can help

• Are you using Go modules?
• Can you try the navigation in the editor and then compare that with running godef on the terminal? This way we can see if godef -t -f your-file-path -o offset itself is taking the time or if the extension is doing something wrong.

The godef tool will need offset which you can get by using the show-offset extension

yes ,i am using go mod.
As your suggestion, i try to navigate by godef which takes minutes to get an result.
What's more, i don't get an result using the navigation in the editor，then it remind me to update my godef.

Do you get the result after updating godef as per the prompt?
After updating is there any difference in the speed in VS Code as well as when you try godef directly?

Same issue here, when I use vscode-go with vgo projects it got unbearably slow to use intellisense (~10 seconds and mostly results in failure).

godef takes ~2 seconds for me (is it normal?):

$ time ~/gotools/bin/godef -t -f main.go -o 6037

@ahmetb That looks suspicious. Please log an issue in the repo for godef and loop in rogpeppe and ianthehat in the issue

Closing this issue due to below reasons

• An upstream issue has been logged for godef
• We now recommend using the language server gopls when using modules.
