17 © 2007 Citrix Systems, Inc. — All rights reserved What Causes Poor Application Performance over the WAN? Network latency (distance) The greater the distance, the worse the application performs Bandwidth utilization drops exponentially as distance increases Accessing in Seattle from a server in Orlando can take up to 80 times longer than from a server in the same building! In the same city San Francisco to Los Angeles San Francisco to Chicago San Francisco to Miami
