Has anyone ever compared different LDAP servers? I am currently planning to upgrade ADAM to another server, and I'd like to know how do they perform.

Currently the options that I am researching are:

Active Directory (LDS)
OpenLDAP
Red Hat Directory Server
OpenDS
OpenDJ

edit: I am looking for any kind of measurement that has been done. Anything as basic as reads/writes per second. I am looking for any quantitative measures to support choosing any of the servers above for my upgrade.
