Image Caching Page
The Image Caching page (FIG. 90) 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.
