After tracking down this I ended up here
https://github.com/vuejs/component-compiler-utils/blob/442d7b221d2075b2b53d8f6d4e1a4b4e6ab911e3/lib/compileTemplate.ts#L167-L178

that's why it takes so much time in dev mode.
I don't know if this should be reported to prettier or not

The issue prettier/prettier#4784

[nblthree]

A work around is to set prettify: false in vue-loader options

[lubien]

This should be fixed in the next release, no ETA yet, probably in a couple of weeks, but I'll try to cut one before that
