Use cache instead of saving to database With my plugin I am generating and saving a lot of data to a secondary table. Data that can be generated on the fly that is associated with entries. I have noticed a performance hit and was given a suggestion of caching some of that data instead of writing to a database.  

Does craft have a built in caching system I can use for accomplishing something like this?
craft()-&gt;cache can point to any one of several different caching drivers as defined by the   cacheMethod config setting.

The available methods are all pretty much stock Yii provided caching drivers, with the exception of FileCache, which we've extended a bit.

Note that FileCache is used by default and its values are saved under the craft/storage/runtime/cache folder.
