Variable: dired-omit-localp
dired-omit-localp is a variable defined in dired-x.el.gz.
Value
no-dir
Documentation
The LOCALP argument dired-omit-expunge passes to dired-get-filename.
If it is no-dir, omitting is much faster, but you can only match
against the non-directory part of the file name. Set it to nil if you
need to match the entire file name.

;;; Omitting
;; Enhanced omitting of lines from directory listings.
;; Marked files are never omitted.
