Image Caching Page Elements (Cont.)

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 that is 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.

Setting the image cache

In the Protected Setup page:

1.Press the Cache button in the Protected Setup Navigation Buttons section. This opens the Image Cache page.

2.Set the cache expiration in the field Flash/RAM Cache Expires. The Up and Down arrows increment through the available time frames.

3.Press the Enable button to turn on image caching. The button appears illuminated when enabled. You can allocate Flash memory for image caching, but RAM cache is always enabled.

Select the Up and Down arrows for the field Flash Cache Size to increase or reduce the amount of Flash memory used; the maximum amount of flash that can be allocated for caching is 75% of available flash.
