+1 this issue. All these godef processes really eat up my CPU and don't leave me with much anything else. Please fix this bug!

@zakokun, @ameissnersofi Did you both recently upgrade to Mac OS X Sierra?

There is a known issue of performance on Mac OS X Sierra. See #503

Run the command Go: Install Tools. That should update all the go tools that the extension depends on which should fix the issue

[ameissnersofi]

Yes, I did upgrade. I can't remember how long ago, but this all seems to be connected because delve debugger is also having trouble on Sierra.

I'll run this command first thing in the morning and report back. Thanks for responding so quickly!

[zakokun]

yes! I updated those tools and it fixed! I can use vscode again. thank you very much~ @ramya-rao-a

@ramya-rao-a yes! I'm sorry, I meant to respond sooner. I've got my team back up and running on vscode again. Thanks so much!!!
