How can creating the SessionFactory become slow after updating Hibernate?
- by DR
In my Java SE application I used Hibernate 3.4 and creating the SessionFactory took about 5 seconds.
Today I updated to Hibernate 3.5.1 and suddenly it takes over a minute.
What can be the cause of such a dramatic effect?
I tried different things the better part of the day and I have no clue...
Some data I collected
According to the profiler the most time is spent in PersisterFactory.createClassPersister and in that method ProxyFactory.createClass takes the most time.
The log shows nothing unusual
Changing hibernate.bytecode.use_reflection_optimizer makes no difference
