I’m not even sure what I need to attach to

@TUKenStone sorry, what I mean was there is a file at /Users/ken/Dart-Code.dart-code-unresponsive.cpuprofile.txt that VS Code created when it gave you this warning, and you are supposed to attach it to this GitHub issue. It’s a CPU profile of the extension code, which will show what code was running when this happened.

Unfortunately I can’t reproduce this issue (though my machine is very fast). I’ve had a few people raise it in the past, but none have ever attached the CPU profile, so I’ve never been able to investigate where the time is going.

If you can attach that file (which I believe VS Code has sanitized to ensure there is no personally identifiable info, pathnames, etc.) I can investigate. If you’d rather share it privately, you can email it to logs@dartcode.org.

Thanks!
