Image Caching Page
The Image Caching page (FIG. 83) configures the allocation of memory for image caching. The G4 graphics
engine caches images to decrease load time of previously viewed images. RAM caching is always enabled,
and images (both static and dynamic) 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 it is typically faster to retrieve images on Flash than across a network
(although it is slower than 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.
