Hi Howard,

Thanks for the slides, there are interesting numbers in it, though not 
very pleasant for us ;)

Is it possible that you post the configuration you have used for A2pache 
DS (server.xml, and java version ?).

Very true. We have worked on correctness first too, and we are not 
finished yet, but performance is also somewhere back in our mind. It 
takes time to get correctness, and if you are not starting with a lot of 
experience like Sun guys did (they have SunDS running for a loooong time 
before they started OpenDS), you have to dedicate a lot of time on 

Just expect to see ApacheDS improving by a large margin in the 
performance field in the next few months (hey, we have a wide margin for 
improvment ;)

It could be interesting if we can share the very same tests so that the 
comparizon would be fair.

If you are going for a new injector tool, then may be we can share some 
ideas about it. Basically, I buy the idea.

Thanks for the feedback !
