Gather data, plan, and then implement

The first step in developing a plan for cache usage is to provide as much memory as possible for the data cache:

Determine the size of memory you can allocate to data caches as mentioned in the above steps. Include the size of already configured cache(s), like the default data cache and any named cache(s).

Decide the data caches's size by looking at existing objects and applications. Note that addition of new caches or increase in configuration parameters that consume memory does not reduce the size of the default data cache. Once you have decided the memory available for data caches and size of each individual cache, add new caches and increase or decrease size of existing data caches.

Keep your performance goals in mind as you configure caches:
