It Shows which individual filters cannot be cached by marking them with an asterisk on the format configuration page and shows which formats cannot be cached by appending an asterisk to their names.
An input format consists of one or more input filters applied consecutively.
The text you input (for example the body of a node) is usually processed by several input filters - those that are enabled in the format that you selected when you input the text.
This processing may take significant time, which is why Drupal tries to cache the result so that the processing does not need to be repeated unnecessarily.
However, the output from some filters cannot be reliably cached (the PHP evaluator is an example).
Using such a non-cacheable filter prevents caching for all text which uses that format whether or not the functionality provided by the non-cacheable filter is actually needed. Clearly it makes good sense to avoid using a non-cacheable filter format unless it's really necessary.
There is no obvious way to see which formats can be cached nor which individual filters can be cached. This module provides that information.
