Citrix XenApp Performance Essentials

Book Description

A practical guide for tuning and optimizing the performance of XenApp farms using real world examples

  • Design a scalable XenApp infrastructure
  • Monitor and optimize server performance
  • Improve end user experience
  • Tune the farm for WAN connections
  • Real world examples, ready-to-use suggestions, and best practices

In Detail

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.
