Blogging Roller: Hibernate twice as fast as Castor?

Hibernate twice as fast as Castor?

I did some stress testing of Roller 0.9.7 last night with JMeter and used it as an opportunity to compare throughput of Roller with Castor vs. Roller with Hibernate. I put a summary of the results on the WIKI. Any suggestions for improvement on this test or comments on the limitations of this test are welcome.

Part of the reason I was testing was that Matt has been having severe problems with out-of-memory exceptions. After running those tests, I let JMeter run the test plan all night long (Loop Count: Forever) and enountered no out-of-memory problems. I guess I need to get closer to Matt's config if I want to duplicate the memory problems he is encountering.

Dave, can you post the JMeter test script somewhere (you can save a script right? its been awhile...). I'd like to see how it compares on Resin, and I also want to see if changes to Castor's cache settings make much difference (I've got "issues" with the default settings).

The Hibernate FAQs and performance sheets do list that they have seen concrete evidence that it is significantly faster than 'those other O/R mapping strategies'. It wouldn't surprise me if it was; I'm always extremely impresses with the performance myself. R.J.
