Benchmark that matters is the one you perform.

And I bet they also said that running Microsoft products has a lower Total Cost of Ownership than anything else too.

The person making those claims ought to provide the evidence backing up the claims. (If they can. Most likely not.)

 I have no specific performance numbers for AD, however I would note
 that the only study I know comparing the two was done against
 OpenLDAP 2.0, and is extremely out of date.  The newer releases of
 OpenLDAP are hundreds of times faster than the 2.0 release when
 configured properly.


 has some more recent numbers, and we are working on a more
 comprehensive set of benchmarks.
