100% CPU load

[antirius]

100% CPU utilization in large projects .. In which there is no XML!

That's very strange because the XML Language server is started only when a XML file is opened. Could you share your project or provide a similar project which causes your issue. Thanks.

[antirius]

Apparently the problem is that an xml file was opened in one of the windows. At the same time, several copies of VS Code were launched (4 copies, each containing 3-15 project directories).
Does he start scanning everything not only in the current project?

It seems to start scanning all these directories

[angelozerr]

Could you share your project please?

[antirius]

Unfortunately not. The only thing I can say is that there are a lot of files. Plus these are nodejs projects, and there are even more dependencies in node_modules.

It's very hard to help you without a project which causes your issue.

Could you add in your settings.json add "xml.trace.server": "verbose" and share the XML Support Output:

when your issue will come back.

To understand what is slowing down, I had to kill java (delete from disk), and then the XML extension error got out)
Next time I install it, I will definitely try the tracing and drop the log, thanks!)

Is this still reproducible in the latest vscode-xml ?

The 100% cpu load seems similar to eclipse-lemminx/lemminx#1175 . It happened when xml.validation.enabled was set to false. In addition, we have made a lot of performance improvements in the 0.21.0 release

Closing this issue as I suspect it was fixed some time ago. Feel free to re-open if it persists.
