it's very very slow for parse and highlight vue file

[coader]

after upgrade to latest version, it's very slow then before

[afv]

For me, vue-tsc --noEmit -p tsconfig.vitest.json --composite false takes 1 minute to run on 2.0.7 and 48 minutes on 2.0.10/2.0.11. Any idea on how to debug this?

I'm experiencing something similar. I tried to run vue-tsc with --extendedDiagnostics and looks like 2.0.11 is taking more memory compared to 2.07. I don't know if that has something to do with it.

Here are some screenshots of the diagnostics results on few projects.

So slow there is no desire to use

Same issue here, Since updating to the latest version our CI build fails and throws folling error:

Running it localy is also very slow.

Is this one still an issue in the latest 2.x? Can you provide a repo so we can investigate?

@davidmatter I believe this was fixed a few releases after 2.0.11! I think it's safe to close this one 😊 Thanks to whoever looked into it!
