Anyone else using the Search List as their phone directory?

We're having major issues doing a list of all the phone book entries
(5,000).

The portlet times out after about 5 seconds (even though it's set NOT to
have any timeout)

Then when we try to export the results, it takes over an hour and the
overall session times out

I'm puzzled as to why it's taking so long when it's basic LDAP stuff
with some pretty graphics around it.

Or am I the only one using it as a phone book and wanting a nice printed
list?
