Are you thinking of queries?
Axel is speaking of regular files in a folder.
Sure, you -could- limit the number of files displayed,
but is there any system that does?
Slow lookup is not enough reason to do it.
Metadata-based searches may benefit from it, maybe.
(Search, refine, display. Incrementally.)
You can do other tricks to improve the illusion of speed,
like letting visible items have their metadata updates first,
and improving the listviews' datastructures so they don't
slow down exponentially with larger amounts of files.
In the case of column listviews you could post-pone lookup
of all attributes except the one(s) sorted by, to have the
listview populated and settled (at peace) quickly.

I'd say it seems you're thinking inside the web.
(SQL, PHP, search results..)
