Cache is used for different things that are I/O intensive. The main use of
cache is for entities to reduce the number of database queries, which will
be the slowest operation of all. In practice, a few entities are accessed
very often and rarely change, so it creates an ideal opportunity for
caching.
Cache is also used for things that would have a lot of disk access, like
Screens.
The entity cache is actually very simple and easy to understand. Have a
look at framework/entity/src/org/ofbiz/entity/cache/EntityCache.java and
think about how an instance of this is used by the Delegator.
