Vscode: 100%+ CPU usage from "Code Helper".

[lukasz-formela]

Issue Type: Performance Issue

From my research it can be something about "files.watcherExclude".

After running my VSCode instance ( many files in the folder that I open with it ) the fans start to roll out that 6k RPM and CPU goes to 100% usage.

VS Code version: Code 1.33.0 (0dd516dd412d42323fc3464531b1c715d51c4c1a, 2019-04-04T15:11:32.076Z)

Try rm -r ~/Library/Caches/TypeScript/3.4 and restarting VS code

There was an issue with styled components and the typescript issue that was causing this to occur. It helped fix the issue for some but not others. It's worth a shot. See https://github.com/Microsoft/vscode/issues/71886 for more info

Was worth a shot but sadly didn't help.
In two minutes after opening VS code it goes to 4th density mode.

I added the suggested temp folder but still there's no change.
**/tmp/**

[steveoOn]

the same issue happened on me, macOS 10.14.4, vscode 1.33.0, now I can only use the old version 1.32.3 and disabled the automatic update. Tried "files.watcherExclude" but nothing changed.

[soorajvnair]

Yes. Same here. Switched to an insiders build, works fine.

A little additional info:
If there is a chance to see what changed with last update (i don't mean
changes overall, but to my instancje of vs studio- like a log/historyczne
what was added with update).
It all started with me updating VS Code.

Hey all, I had the same issue after upgrading to version 1.33, but after letting the program run for a little while, the CPU usage is now back to normal.

[lukasz-formela]

Please use this guide to provide more information: https://github.com/Microsoft/vscode/wiki/Performance-Issues#profile-the-running-extensions. Thanks.

What if:
[Public-:~ $ code --inspect-extensions=9993
-bash: code: command not found] ?

Small update:
Overheating starts when 'Initializing JS/TS language features'.
I'll try to follow @jrieken instructions.

❗️ and everyone update to 1.33.1 first, there has been an issue with TS/JS which might have caused this

That sounds reasonable, the CPU profile point to S?CSS parsing and it will then be one your installed extensions (maybe scss-lint). There is nothing we can do here, except asking you file an issue against the extension.

[GeorgiosP]

code helper seems to be consuming 100% of cpu with no extensions included. 😕

[jrieken]

I am closing this as caused by extension because the only actionable provided information is from @lukasz-formela and the profile showed that this is an extension.

Unfortunately, other me-too-comments without further information aren't actionable.
