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.

Creating a worker group

To create a worker group, right-click on the Worker Groups node in Citrix AppCenter, and select Create worker group.

You need to give a name to the new worker group, an optional description, and select the source of the servers:

  • Active Directory Containers

  • Active Directory Server Groups

  • Farm Servers

A worker group can either be static or dynamic. If you choose Farm Servers, you can manually add one or more servers to your farm. Choosing an Active Directory option instead lets you "link" the worker group to an...
