| Doc Text: |
There is a performance impact if you use the same stateful knowledge session across multiple process instances. This is because the one-session-for-all-processInstances model is inherently single threaded. When the transaction is started, it will pessimistically lock the SessionInfo table, blocking other threads.
To avoid this, create mapping so that a session is only ever used for one process instance and use a unique JPA entity manager.
