Prettier much slower when using this plugin about prettier-plugin-organize-imports HOT 3 OPEN

Hey thanks for reporting! Might be a performance regression (already had two of those iirc, might be time for some performance tests 🙈).

This function from typescript being very slow was the problem last time so I added memoization.

If neither you nor someone else would be able to drill down on this, it'll probably take me some time to get to this, maybe next week.

Hm ok by just looking at the code a bit, i think I might have figured it out already. findTsConfig gets the path of the file being formatted, which obviously is different for every execution (unless you format the same file twice), so the memoization never really does anything (when I introduced the memoization, it did fix the performance problem though 🤔).

@simonhaenisch Is not it better to find all tsconfig paths and just use search inside of the array and use most similar path. How much performace cost has findConfigFile?
Btw, findConfigFile in typescript is not optimal at all if used for more than couple files
