3.4 Bandwidth Effects on Usability
ClearCube Technology, Inc. 23
Non-interactive usage: For USB devices, increased latency nearly linearly affects the
performance of the device. For example, in the figure below, transferring a 4-MB file to a USB
drive, the following numbers can be seen by stepping through latency increases.
NOTE: Although WAN acceleration products cannot affect the video portion of PCoIP traffic, they
can optimize and improve USB performance.

3.4 Bandwidth Effects on Usability
PCoIP bandwidth issues can cause image quality loss and frame loss.
The higher the bandwidth is in your environment, the better the performance of your PCoIP
devices. Note that PCoIP systems perform well when performing complex tasks in environments
with lower bandwidths. The key to determining system usability is
 identifying how sensitive users are to Windows desktop experience settings (for example,
disabling Aero, using only outlines of moving windows, non-animated menus, and so on)
 temporary blurring for rapidly-moving items, and
 pixilation of moving items when many things are happening at the same time.
