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.

CPU Utilization Management


If you're analysing the performance of your farm, in search of possible bottlenecks, you'll most likely find lack of CPU or memory resources.

Citrix CPU Utilization Management is a feature you can enable to improve the way XenApp manages CPU resources and to normalize CPU peaks.

Note

CPU Utilization Management is a feature included in the Enterprise or Platinum edition of XenApp.

When you enable CPU Utilization Management, the server checks the proportion of CPU resource (share) assigned to each user. By default, it assigns the same share to all the users. This prevents one user that executes CPU-intensive operations from impacting the other users on the same session-host servers.

For example, consider a user who is using a spreadsheet to perform complex financial calculations. Without CPU Utilization Management, his session will probably be consuming most of the CPU resources available on the server, slowing down the work of other connected users. With CPU Utilization...
