Yes it was a read-only test. But then that's the main application of
LDAP servers. Are there applications that require high LDAP write
performance?

I found the other benchmark paper here:

http://highlandsun.com/hyc/SambaXP.pdf

It includes figures for FDS. A summary can be found here:

According to that paper, OpenLDAP pretty much blows away everyone else
in performance and scalability. Nothing else is even close.

Of course it is a benchmark. I'm sure someone will find some flaws :-)
