Up to 300 times slower than when not using paged results: Without paged results: time ldapsearch -LLL -x -H ldap://zre-ldap002.eng.vmware.com -b "ou=people,dc=xxxx,dc=com" -s sub -D uid=zimbra,cn=admins,cn=zimbra -w zimbra '(objectClass=zimbraAccount)' uid real 0m0.004s user 0m0.010s sys 0m0.000s With paged results: zimbra@zre-ldap002:~$ time ldapsearch -LLL -x -H ldap://zre-ldap002.eng.vmware.com -b "ou=people,dc=xxxxx,dc=com" -s sub -D uid=zimbra,cn=admins,cn=zimbra -w zimbra '(objectClass=zimbraAccount)' uid -E pr=1000 real 0m1.204s user 0m0.010s sys 0m0.000s Using paged results is fairly standard in Java clients, to prevent them from hitting OOME's based on the way in which results are returned into a single object.
