Hi Howard,
Howard Chu a écrit :
For anyone curious, the slides from my presentation at the SambaXP
conference last week are now up on my web site.

Thanks for the slides, there are interesting numbers in it, though not
very pleasant for us ;)
Much of the material on malloc benchmarking was already presented at
SCALE5x earlier this year. New material in these slides include
benchmark results for OpenLDAP 2.3.34 vs FedoraDS 1.0.4, OpenDS 0.1-34,
and ApacheDS 1.0.1 on Linux 2.6. The machine used for these tests is the
same SunFire X4100 used in these tests last year

Some earlier discussion of these results is also on the Connexitor blog:

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

Another thing to keep in mind - unlike FedoraDS (and Sun DSEE), OpenLDAP
is fully RFC compliant, does full schema checking, and fully implements
the X.500 data model. It does all that and is still over 3 times faster.
It's not just about speed; correctness still comes first. With good
engineering you don't have to sacrifice correctness to get performance.
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
correctness.
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 !
PS: keyboard is dead :( RIP.
