This is the cause of the problem:
(defvar grep-mode-font-lock-keywords
'(;; Command output lines.
(": \\(.+\\): \\(?:Permission denied\\|No such \\(?:file or
directory\\|device or address\\)\\)$"
1 grep-error-face)
With that removed, everything's nice and fast. Limiting that .+ to 200
characters also makes things fast:
diff --git a/lisp/progmodes/grep.el b/lisp/progmodes/grep.el
index 17905dec2e..7620536b4b 100644

;; remove match from grep-regexp-alist before fontifying
("^Grep[/a-zA-Z]* started.*"
But I guess the real question here is still why we're font-locking
invisible text.
