Well, its faster, in our case (and I say that tongue-in-cheek).  Our current
primary directory server is running on a dual 168Mhz Ultra 2 Sun box.  And our
secondary is a Sparcstation 10, at a whopping 70Mhz :)

Its a small installation, maybe 10,000 entries, but that services our own
organization, as well as 22 school districts, each in separate trees.  But per
above, there's really no way I can provide an accurate comparison between the
current and anything else, other than to say its faster.

Factors that go into my decision (and I use Fedora loosely, to describe my
experience and observations with Netscape/Sun/iPlanet products generally):

Cost (its a wash between OpenLDAP vs. Fedora DS)
Manageability (hands down Fedora, simply because I'm familar with the Netscape
management infrastructure)
Scalability (my guess is Fedora, based on the size of installations 
that are out
Availability (Fedora - no proven multimaster support in OpenLDAP)
Ease of migration (Fedora - an upgrade to OpenLDAP meant refactoring 
all ACL's,
massaging attributes and objectclasses, etc.)
