Kamil, It seems that the cache is working, in the log I see 'cache hit'. But I am very disappointed because the performance is equal and in some cases worse than without cache. And the sql queries continue to appear in the console, which seems strange. I know that the cache is not a silver bullet, but in this case, leaves much to be desired. Is there any explanation for this poor performance? thank-you View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4167172#...
