Bandwidth Spikes Impact E-mail Performance for Users

Delivering applications in a client/server architecture can cause bandwidth spikes and degraded performance when the client requests large amounts of data from the central data storage network. The Microsoft® Outlook® and Exchange model of client/server delivery – as well as Outlook Web Access – are both susceptible to large spikes in bandwidth consumption. With Exchange being a market leader, and with increasing numbers of remote/mobile workers requiring e-mail access, the need to address these bandwidth issues is more important than ever. Microsoft Exchange customers face the following application performance challenges:
  • Provide high e-mail performance to remote and mobile users
  • Enable offshoring to areas with inadequate and costly bandwidth
  • Avoid cost of purchasing high-bandwidth connections
  • Accommodate mobile technologies with limited bandwidth
  • Reduce user frustration that can increase help desk calls
Citrix Presentation Server™
Current Environment:  Microsoft Outlook and Exchange Client/Server Model. Outlook users connect directly to the Exchange Server for e-mail, and Outlook Web Access users connect directly to the Outlook Web Access Server, which in turn connects to the Exchange Server, resulting in slow performance and high bandwidth consumption.

Benefit

In a test environment, accessing e-mail via Citrix XenApp reduced Outlook bandwidth by 28% and Outlook Web Access bandwidth by 79%.
