Flash/RAM Cache Expires
Press the Up and Down arrows to change the amount of time the images stay in
cache memory. The options are:
• Never
• 2 Hours
• 8 Hours
• 1 Day
• 2 Days
• 5 Days
Enable:
Press this button to toggle the image Flash cache option On and Off.
Clear Cache:
Press this button to clear both the Flash and RAM cache of all stored images.
Image Cache Status:
The status of the memory available versus in use.
RAM Max Size
The maximum amount of memory available for all image caching.
RAM Current Size
The memory currently in use for caching static and dynamic images.
RAM Hit Rate
The percentage of image requests (static and dynamic) satisfied by accessing
the cache.
• 100 * (# of cache hits) / (# of cache hits + # of cache misses)
• # of cache hits - the number of times an image was requested that the image
was found in the cache
• # of cache misses - the number of times an image was requested that the
image could not be found in the cache, and the image had to either be loaded
from flash or obtained via the network (for dynamic images). It is considered a
RAM Cache Miss even if the image is subsequently found in flash cache.
Items in Cache (RAM)
The number of images that are currently stored in the RAM cache.
Flash Current Size
The maximum flash space allocated for image caching.
Flash space is used for caching only when there is not enough available
memory in the RAM cache for a newly requested image (it is used only for
dynamic images).
Flash Hit Rate
The percentage of image requests (dynamic only) that are satisfied by
accessing the flash cache.
• 100 * (# of flash cache hits) / (# of flash cache hits + # of flash cache misses)
• # of flash cache hits - # of times a dynamic image could not be found in RAM
cache but was found in flash cache
• # of flash cache misses - # of times a dynamic image could not be found in
either RAM or flash cache. RAM cache hits are not relevant in this calculation.
Items in Cache (Flash)
The number of images that are currently stored in the Flash cache.
