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 E-mail in Seattle from a server

in Orlando can take up to 80 times longer

than from a server in the same building!

Common SharePoint Portal Server Tasks

• All routine SharePoint tasks are accelerated with the addition of Citrix NetScaler and Repeater

• MySite pages load 74% faster

• File downloads improved between 33% and 87% as file size increased

• As user’s connections get worse (remote, satellite, etc), performance remains consistently fast

• Previously unusable scenarios suddenly become high performance!• What would take 10+ minutes without Citrix now

happens in about 10 seconds

SharePoint - High Latency Scenarios

• Low bandwidth, high latency, and packet loss all contribute to poor user experience

• Citrix Repeater removes those barriers by managing data transmission and optimizing performance for connectivity challenges

• Being “connected” doesn’t equate to being “productive”
