[JBoss Cache: Core Edition] - I don't Think I am doing this Correct - jboss-user

Tuesday, 18 March 2008

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?
