Subject [jira] Created: (OPENJPA-439) Performance degradation in multi-transaction operations
Date Sat, 10 Nov 2007 00:44:50 GMT
Performance degradation in multi-transaction operations
-------------------------------------------------------

                 Key: OPENJPA-439
                 URL: https://issues.apache.org/jira/browse/OPENJPA-439
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 1.0.0, 0.9.7, 0.9.6, 0.9.0, 1.0.1, 1.0.2, 1.1.0
            Reporter: Patrick Linskey
             Fix For: 1.1.0


Reusing a Broker for multiple transactions / persistence contexts demonstrates a performance
degradation, possibly due to explicit calls to clear sets and maps, rather than just dereferencing
them.
