Thanks for reporting this.

I loaded the profile but the first 358ms are empty. The last 2ms show some activity but nothing that looks concerning. I wonder if that is because we use an LSP?

We also bundle our extension, and the profile doesn't look like the Code Loading graph

Can you tell me more about what operation you were performing when vs code asked you to report the high cpu load?
