This is a proper bug report for an issue I raised on emacs.devel:

When marking multiple files in Dired, then running a search with
`dired-do-find-regexp', `xref-collect-matches' is called once per marked
file, when it could just be called once for the whole search. This can
slow things down quite a bit.
