Dear Tim Thanks for helping me a lot. Let me answer your questions.

The performance test was conducted on June 23th and I experienced the slow ActiveMQ issue on that day. This is the current kahadb data file directory list. (not June 23th) I didn't log the growth rate of Kahadb data during the performance test. I'm sorry..
