Your users won't ever see all 5000 records at the same time (they'll
be "clipped" by the screen/window size), so don't send them all in one
shot.
As for the UI, you have several options:
- use "pages", fetching and showing one page at a time (prev, next,
go to page #N; as in Google/Bing/etc. search results)
- use "more" buttons to fetch the next "page" of records and append
it to the already retrieved ones (as in Twitter or Facebook)
- use an "endless scroll" (similar to "more buttons" but triggered
automatically as you scroll down the page; as in Google Reader)
Have a look at the PagingScrollTable and bulk table renderers from the
GWT Incubator (I'm not sure but I think they're used in Google
Adwords):
