Protected Setup (Other Settings) - Cache Page

Select Cache from the Other Settings slider to access the Cache Page (FIG. 74):

The options on the Cache page allow you to configure the allocation of memory for image caching.

G4 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 be moved to Flash, since it is

typically faster to retrieve images on Flash than across a network.

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.

While RAM cache is always enabled, Flash memory can be also be allocated for image caching. However,

Flash memory is a secondary cache and is much slower than RAM cache (as it uses the local disk to store

images).

Flash memory should not be used frequently, but it may be appropriate to use Flash memory in some

environments that are dynamic image intensive, at times when RAM cache is easily exhausted and the time

taken to access Flash memory would be faster than network latency.

For example, when large dynamic images are being used over slow wireless links, putting the images into

Flash memory can improve performance, since the panel can spend more resources processing information

rather than waiting on images to arrive from a slow network.
