There is no configuration in ApacheDS per se, it's about the JVM memory you set when you start the server (or websphere). > 2. I cannot give you exact numbers, only if I enable logs. Rough estimation is good enough. There is a huge difference between 2 additions per second and 200... > What I can say, that there are four parallel servers doing writes...

So Writes up to 4 servers, reads up to 10 servers (4 > as app reads, 10 as infrastructure reads) FYI, you have to know that while a server is writing, nothing else can be done (including reads). If you have clients poudning the server with writes, then it's likely that the other clients will be blocked, and in this case, it might have some impact on the performances. -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com
