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 caches, like the default data cache and any named caches.

Determine data cache size by looking at existing objects and applications. Adding new caches or increasing configuration parameters that consume memory does not reduce the size of the default data cache. When you have decided what memory is available for data caches and the size of each individual cache, add new caches and increase or decrease size of existing data caches.

Keep performance goals in mind as you configure caches:
