I am playing around with JBOSS Cache and do not know if I am doing this correct. When I
do a FindAll....I can see that the cache is populated when i do a printDetail in the
JMXConsole. However, when I do bench testing and keep calling the same method,
FindAll..., I do not seen any performance increase. Is it still making a call to the
database? It takes the same amount of time as non-cached implementation. Below is the
entity i am using. It's a view in one of our tables that contains abour 20,000+ rows
that I would like to have cached.
Taken from Hibernate tutorial - : This call actually will fill the cache when it is first
run. but as I do consecutive calls to this, i do not see a performance increase. They
all take the same amount of time as the initial call. Is this the wrong thing to do?
