Subject [jira] Created: (OPENJPA-342) Performance of flush()
Date Wed, 29 Aug 2007 10:09:30 GMT
Performance of flush()

                 Key: OPENJPA-342
             Project: OpenJPA
          Issue Type: Bug
         Environment: Windows XP, jdk1.6.0_02, Kodo 4.1.4, Ms sql server 2005, jTDS 1.2 database
            Reporter: Christiaan

Based on the discussion in thread
I've created a testcase, which is attached. It includes a "Performance results flush.txt"
which gives an overview of the the performance results. In general, using flush() within one
transaction with many changes the performance drops quite significantly (x 15). 

Btw, not sure which OpenJPA version this is. It is based on Kodo jdo version 4.1.4
