It is not so much a matter of quantities but a matter search
frequency.  I have for example 2 dynamic lists with some 9k entries
each and the search results are quite sufficient:

time ldapsearch -Y external -ZZ -H ldap://localhost -b
"cn=dynamicgroup,o=avci,c=de" -s base "*" 

real    0m2.236s
user    0m0.028s
sys     0m0.016s

But the search is done quite rarely. so it wouldn't have any influence
on the overall performance, but if such a search would occur quite
frequently, say a few searches every second, than this would have a
bad influence on performance.
