Benchmark that matters is the one you perform.
Yes and no. Certainly, taking at look at how things perform for what you
plan to deploy can be quite useful.
However, if you set up your benchmarks where you document well what you did,
and make sure that your configuration settings are public, you can set up
benchmarks that others can duplicate, and can be agreed upon as indicative of
real meaning. Certainly testing AD on a Pentium II with 1MB of RAM and
OpenLDAP on a dual CPU 3.2 GHZ Xeon with 16GB of RAM wouldn't be a fair
comparison. Qualitative statements about the general performance of any set
of given Directory Servers can be made if you make everything "the same" as
much as is feasibly possible.
I do not see this being realistic. You have fallen short in this regard
with your Symas benchmarks. Yes, benchmark results can be used as a
general performance indicator, but one should not assume that their ldap
deployment will perform the same. We all have our own requirements,
different machines, schema, data set size, indexes, etc., and more than
likely they are different than what is used in benchmarks.
