Hi all,
I am using v22branch and I am experiencing a long time to startup hibernate. I've read something about serialization implemented in version 2.2 but I don't know if its enabled by default or if I should set some property. I am loading 2 simple one-to-many collection classes.
Is there any improvement in startup speed?
All the code to initialize hibernate and to use it has been generated automatically by Hibernate Synchronizer. AFAIK there should be much difference in speed if I just did my initialization procedures. There is no overhead introduced by Synchronizer.
Here are my hibernate xml files (the attributes are in portuguese, but I guess this is not a problem):
Code:
