In fact, RHEL3 has yet to meet our performance targets (whereas RHEL2.1
with almost any openldap version on any database backend does).
Check your libc versions. We've had problems with Glibc 2.3.2 running
WAY slow compared to 2.2.5. This seems to be tied to changes in the
regexp(3) functions to support multibyte. If you issues are showing up
doing substring searches, I bet you've got the bug too. See the thread
in this list with the subject "OpenLDAP performance and Glibc under
Debian". Hope this helps
