Start with providing useful information:

What openldap version are you running?
Which openldap backend are you using?
Have you correctly indexed the attributes being used to filter on?

I would also note that if you are going to do something like sn=t*, you may 
need to play with the index lengths for substrings, as documented in the 
manual page.  IIRC, they default to triplets.

etc.
