User manual

The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the bottom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
Because during scrolling, the display information sent to the client device is primarily a sequence of cache
indices, using the image cache saves a significant amount of bandwidth. This efficient scrolling has benefits
both on the LAN and over the WAN.
n
On the LAN, where bandwidth is relatively unconstrained, using client-side image caching delivers
significant bandwidth savings.
n
Over the WAN, to stay within the available bandwidth constraints, scrolling performance would be
degraded without client-side caching. Over the WAN, client-side caching saves bandwidth and ensure
a smooth, highly responsive scrolling experience.
With client-side caching, the client stores portions of the display that were previously transmitted. The cache
size is 250MB.
If you use View 5.2 servers and desktops, a 90MB client-side cache gives the equivalent performance of
using a 250MB cache with earlier versions.
