If you just want a memory-only cache, then you do not need Disk Cache
(DC) nor lateral cache (LTCP).

As for the concepts, they are explained at
http://jakarta.apache.org/jcs/getting_started/intro.html

Subject: JCS data retrieval is slower than database!!

Hi,
  =20
  I am trying to get a grip over JCS. I am able to get it working but
not sure what I am doing wrong. I am putting 1000 objects in JCS. While
retrieving these data, JCS is giving slower performance than what
database is giving. Following is my configuration file. Any idea, tip,
suggestion is greatly appreciated. Also, could you refer me to any study
material about JCS. The terminologies like region, LTCP, DC are not very
clear to me.
