I think they are right. The performance test (perf-test task) for odmg-api took 43 sec with rc4 (27 July) took 37 sec with new DList implementation (1 August) took 55 sec (ca. 25 Sep) took 48 sec after fixing lock cleanup (today) So performance of odmg-api decrease more than 30% between 08/01 and 09/25! I couldn't find out the reason for that. Seems that the changes made in odmg classes between this period are minor. Maybe the reason are changes in the kernel. But the kernel only performs ca. 5% slower. Any comments, proposals, solutions? regards, Armin --------------------------------------------------------------------- To unsubscribe, e-mail: ojb-dev-unsubscribe@db.apache.org For additional commands, e-mail: ojb-dev-help@db.apache.org
