Hello Armin, you have written in the mailing list, that it takes around 20 sec. to store 10000 objects (is 0,5 obj in 1 ms.). (http://mail-archives.apache.org/mod_mbox/db-ojb-user/200408.mbox/%3C411780E [EMAIL PROTECTED])
In my testszenario, when I logging width timestamp before calling store and also after storing, I see a difference from at least 10 ms till 50 ms for each object.
