Hibernate version: 3.2.0
Ehcache version: 1.2.4
I'm having issues with getting the "caching" behaviour to work. I've just mapped a simple Country business object to my country table in the database and enabled ehcache to cache on this particular table. However, when i load up my page that calls the function to get all countries, there does not seem to be any performance increase after the first hit like i would expect. the outputted log times are as follows (according to the code i've pasted below).
****** Get Country List exec time: 2890ms -- 236 items ******
****** Get Country List exec time: 2109ms -- 236 items ******
****** Get Country List exec time: 2344ms -- 236 items ******
****** Get Country List exec time: 2032ms -- 236 items ******
When i start up my Resin, the logs show that my ehcache provider is enabled, and i see the log message "- read-only cache configured for mutable class: com.gdi.core.businessobjects.Country" so i would assume my Country should be returning from cache after first hit. Is there anything i'm missing or should be doing differently? I've posted details of my current setup including the source code that is getting the country list below. Thanks for any help
