Cache Settings Page
The options on the Cache Settings page (FIG. 81) allow setting and clearing of the flash memory cache, as
well as viewing the status of the current cache settings. The G4 graphics engine caches images to decrease load
time of previously viewed images. RAM caching is always enabled, and both static and dynamic images are
stored in the RAM cache as they are viewed. The size of RAM cache is automatically configured to take into
account available memory versus memory that may be needed by the panel later. As the RAM cache
approaches its maximum size, the oldest items in the cache may be discarded to make room for newer items. If
Flash caching is enabled, dynamic images that would have been discarded will actually be moved to Flash,
since retrieving images on Flash is typically faster than across a network, although it is slower than using a
RAM cache. Note that since static images are already stored on Flash, they are never moved to the Flash cache,
so Flash caching applies only to dynamic images. Images in Flash cache are moved back to RAM cache the
next time they are viewed. As the Flash cache approaches its maximum size, the least recently used items may
be discarded to make room for new items.
