Maybe you can have a look at the memory consumption of a long-running test?! If you run low on memory the JVM starts to trash. Another point to consider is the settings of your JVM ... especially the maximum heap size if you have one defined (-X properties).

Dezember 2003 16:23 An: OJB Users List Betreff: RE: Antwort: WHY OJB SPEND MORE AND MORE TIME TO STORE OBJECTS ? There is no index in my database, only primary and foreign keys. The phenomena still the same with an Oracle 8i database or a SQLServer 2000 database. I removed every attributes in my repository_user.xml using datatype CLOB (ora) or TEXT (SQLServer2000). I removed also every conversions in this file, and all "reference descriptor". i thougth also it was my database but even if i don't delete all datas before running my application. it started with a good speed but it goes wrong. I removed all datas in my database before each storing sequence. The problem lasts. -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Envoye : jeudi 4 decembre 2003 15:50 A : OJB Users List Objet : Antwort: WHY OJB SPEND MORE AND MORE TIME TO STORE OBJECTS ? Hi, is it possible that you have an index on that table??? If you build a complex index every time you insert a set of data your index takes more time. cheers, Ralf "ghielard" <[EMAIL PROTECTED]> schrieb am 04.12.2003 15:23:45: > Hi everybody, > > i have an important problem of performance. > I'd tried every type of object cache (default,empty,perBroker), > i instanciated a new PersistenceBroker instance each time i had a storing > sequence in my java Code, or I kept the same for all storing sequence. > I did it the same thing with MetadataManager. > But it isn't better.
