Description:

JCS is a distributed caching system written in java
for server-side java applications. It is intended to
speed up dynamic web applications by providing a means
to manage cached data of various dynamic natures.
Like any caching system, the JCS is most useful for
high read, low put applications. Dynamic content and
reporting systems can benefit most.
However, any site that repeatedly constructs pages,
dropdowns, or common search results form a database
that is updated at intervals (rather than across
categories continuously) can improve performance and
scalability by implementing caching. Latency times drop
sharply and bottlenecks move away from the database in
an effectively cached system.
