Same here. Two cores pegged at 100% while using the extension, back down to 0% after disabling it.

Looks like the maintainer has been AWOL for 2 years, and hasn't provided any of the people who volunteered with access, so not getting my hopes up.

@alexr00 (sorry, tagging first relevant user I found in the code repo) is there a way to take an extension down from the VS marketplace? This currently has a misleading nearly-5 stars.

@ricardobeat hi, thanks for reaching out. We are aware of this, and this issue has our latest thinking https://github.com/microsoft/vscode/issues/147707#issuecomment-1346260717

If the extension author does not fix this as he promised we might go ahead and mark the extension as deprecated.

[pre]

@isidorn please do that - I just spent some time with VSCode Extension Bisect to identify code-settings-sync being the reason for 100% cpu usage per each VSCode window.

[jnpatrick99]

OMG I've been coding for half a year or so with 90% CPU consumed by VS Code, in a room heated by my desktop and a noticeably increased power bill and thought it was normal. I had frequent crashes and freezes.

After reading this disabled settings sync and it's now around 1-2%. Freezes are gone. Thank you guys.

[isidorn]

@jnpatrick99 cool, thanks for sharing. Just curious - how did you find out it is the settings sync extension. Did you notice it is deprecated in product, or you came across this issue?
