Citrix XenApp Performance Essentials

By: Luca Dentella

Overview of this book

Citrix XenApp is an application virtualization product that allows users to connect to their corporate applications from any device. XenApp can host applications on central servers and allows users to interact with them remotely or stream and deliver them to user devices for local execution. Citrix XenApp Performance Essentials is a practical guide that provides you guidelines, best practices, and real world examples that will help you to improve the performance of your farm, identifying and solving possible bottlenecks and using advanced features including the new features provided by XenApp 6.5. Citrix XenApp is widely used to deliver enterprise applications to end users. This book covers the whole process of optimizing a XenApp farm, starting from the design phase all the way to tuning for remote users and connecting via geographic links. With your farm in production, you will understand what to monitor and how to optimize your farm, as well as how to use an open-source tool, WANem, to test the applications' behavior with different link conditions. You will also learn which settings and features XenApp offers to optimize CPU and memory utilization. This book will help you to prevent or solve performance problems and make your users happy working with published applications.

Chapter 5. Optimizing for WAN Links

If you're administering a XenApp farm for a while, someone has probably already asked you to give access to published applications for users who are not connected to your local LAN. The external access could be for teleworkers, for branch offices, or for outsourcers that even work in a different continent.

The Independent Computing Architecture (ICA) protocol is known for its excellent performance over slow links and its low bandwidth usage. In this chapter you'll learn:

  • The differences between LAN and WAN links

  • The specific optimizations available in XenApp for WAN links

  • How to test your farm's behavior over WAN links before going to production
