MemCacheSize
CacheDir The directory on the Server used to store cached data.

DiskCacheSize Used set the number of elements that can be held in a disk cache at any one time. If the value is 0, the disk cache will not be created.
FlushExpiredInterval Sets how often to check for expired items. (In seconds.)
MemCacheSize Sets the number of elements that can be held in a memory cache at any one time. If the value is 0, the memory cache will not be created.
WriteIndexInterval Sets how often to write the index to disk in seconds. 0 indicates to write on every change.

 

Cache Size Strategy

Content is normally stored in a Cache until it has "expired". However, if the Cache is configured too small, some cached content may be dropped from the Cache to make room for newly cached content. This may result in a drop in performance. For this reason, it is important to configure the Memory Cache and Disk Cache to be large enough to store the most important Content until it expires normally.

Note that items least recently accessed from the cache will be the first dropped from a Cache.
