High CPU nad power usage on Windows 11

[DominikaK]

In version v0.15.2, running on Windows 11, VS Code with this extension causes extensive CPU and power usage.

For example, after about 15-20 minutes or work, with less than 5 files open, the usage is as follows:

Additionally, even after exiting VS Code, high usage remains until I manually kill the vale process:

This issue had not been occurring in earlier versions of the plugin (on the same hardware/software setup), even with many more open tabs and more issues found by vale.

VS Code version: 1.70.1
Extension version: 0.15.2

Can you precise the version of vale binary that you have installed locally?

[DominikaK]

It is: vale version 2.20.0.

After a night sleep, it makes me think like some vale commands started by VS Code extension are blocked in a loop.

What could be useful is:

• find the command-line/parameters used to launch these vale program. We might be able to reproduce then on command-line outside of VS Code. We might be able to find some specific (combination of) files to validate to reproduce the issue
• a thread dump of the vale programs (for which I do not know how to do yet as it is written in go)

After some more investigation, this may be caused by Vale itself, not the plugin, as even with CLI linting a single 400-line markdown file is taking over a minute.

Hi @DominikaK.

I have a similar issue (linked above) but on MacOS.

Can I ask you to try using v2.15.4. Does this fix the problem?
