vue-tsc performance debugging

[plehnen]

In my project vue-tsc takes about 70 seconds.
(according to --diagnostics the "Parse time" is the most time consuming task with 51.21s)

I was wondering if this is due some misconfiguration or expensive types, but I couldn't find a way to get details about what takes so long.

While experimenting and deleting parts of my app I noticed that if I delete the "element-plus" folder inside "node_modules", the execution time is 10 times faster.
I have skipLibCheck active and excluded "node_modules" in tsconfig. So I guess it is not checking the "element-plus" folder, but just parses its types.
So my question is: does this sound like a normal behaviour? Or is there any potential to get vue-tsc to run faster, or to debug where it consumes the most time?
