I have noticed this as well on my Mac as well.

While you're experiencing the problem could you run code --status and paste in the output? This gives a detailed look at the cpu/memory of each of the many processes created by vscode.

This is happening to me as well.. my output is:

`code --status

It seems that disabling 'import cost' plugin fixes the problem.. now back at normal CPU level..

It looks like an extension might be the problem, have you tried running with code --disable-extensions?

Tyriar on 29 Dec 2017

@sietzekeuning the same, it's likely an extension in your case. Try running with code --disable-extensions and if the problem is fixed you can try find the problem extension.

Is there a way to know exactly which extension is causing this?

Math3v on 30 Dec 2017

@Math3v I don't think so, other than disabling each and checking. I'm going to close these off as it looks like an extension is to blame.

We try to keep VS Code lean and we think the functionality you're asking for is great for a VS Code extension. Maybe you can already find one that suits you in the VS Code Marketplace. Just in case, in a few simple steps you can get started writing your own extension. See also our issue reporting guidelines.

Happy Coding!

Not sure what electron_node electronForkStart.js tsserver.js handles but this seems to be what has been throttling my system lately. I guess I'll start going through extensions, but it would be nice if I could determine what that is related to.
