Tooltitude causes vscode to stutter and slow

[vamshiaruru32]

Type: Bug

Recently I have noticed that my VSCode was being extremely laggy and slow. Scrolling a go file with more than 500 lines causes noticeable frame drops and almost makes VSCode unusable. I used extension bisect to figure out what's happening, and turns out it is because of tooltitude. I love the functionality of the extension, but the performance hit is noticeable.

Extension version: 0.46.2 VS Code version: Code 1.80.1 (Universal) (74f6148eb9ea00507ec113ec51c489d6ffb4b771, 2023-07-12T17:20:23.298Z) OS version: Darwin arm64 23.1.0 Modes:

Thank you for your feedback. I am sorry that you have such a bad experience. 500 lines of code isn't the size where it should be slow, I regularly test with files which are much larger, and didn't notice any problems with them.

My hypothesis is that something is wrong with the handling of the file, i.e. panic happens during file check, or code lens production, and it is being repeated again and again.

Could you go to the tooltitude output like on the screenshot and see what's happening there. It shows requests which are being performed and how long they take. In normal situation, nothing should happen, i.e. the files are checked, code lenses produced, but in your case something else is going on. Could you take a look there? (Please don't share output here since it might contain public data)
