A couple of questions:

1. Can the second-level cache (SessionFactory level) be totally disabled in Hibernate 2.1rc1?

2. Is the EHCacheProvider the factory-default caching provider coming from the 2.1rc1 distribution? Do you have a second-level caching implementation turned on by default when using a stock Hibernate system without configuring the cache.provider_class property?

The reason I ask this is I would like to measure the performance of Hibernate when not using any second-level caching at all and then reapply second-level caching and demonstrate a performance gain. This is for a presentation on Hibernate that I am preparing.

Thanks in advance for any help concerning my questions. I been very impressed with the entire Hibernate product, hence my efforts to build this presentation and get the word out about this framework.

No, this is no simple switch. It is possible, however, to do like i do in org.hibernate.test.TestCase and iterate over all mapped collections and classes, calling setXXXCacheConcurrencyStrategy(null), or whatever.

Thanks for the prompt reply Gavin. I can then assume that the net.sf.ehcache.hibernate.Provider is the default cache provider and second-level caching is enabled by default. The documentation on second level caching could be a bit more clear about this:

Thanks again for the information.

second-level cache is NOT enabled by default. It requires <cache> mapping elements in the .hbm.xml or <class-cache>/<collection-cache> elements in the .cfg.xml.
