christian porter added a comment - 16/Apr/06 10:48 PM This issue was created per Erik's request on the following forum thread: http://www.jpox.org/servlet/forum/viewthread?thread=3298 This goal is to find performance issues preventing JPOX from performing at a TPS rate close to plain JDBC in a "flat table" scenario. It seems also that the JDO does not scale as well as JDBC in this scenario also - that is, as we add more client threads the JDO impl (provided in the test case) seems to degrade at an inconsistent ratio. For example, if a single thread is run JDBC performs 2X whereas JDO performs 1X. As we increase thread clients, JDO performs .5X whereas JDBC performs 4X. The goal here is to find these areas of performance degredation.
