Présentation de l'éditeur

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.


A practical hands-on tutorial including multiple examples on application management using Citrix XenApp 6.5.

Who this book is for

Citrix XenApp Performance Essentials is intended for IT architects and system administrators who work with Citrix XenApp and who need an agile, practical guide to tune and optimize the performance.

5.0 étoiles sur 5 In-depth, complete and great reference for XenApp performance tuning 11 septembre 2013
Par Esther Barthel - Publié sur
While writing my own XenApp Cookbook for Packt Publishing, I found the time to read another great XenApp book: Citrix XenApp Performance Essentials. So here's my review on the book.

The book consists of 5 chapters and it starts with design guidelines to IT Architects to design a good XenApp infrastructure. The other chapters in the book focus on improvements and optimizations Administrators can implement to optimize server performance, session start-up time, end user experience and WAN connections.

The first chapter focuses on the design of a XenApp infrastructure, which in my humble opinion is the most important phase for your XenApp infrastructure to determine how it will perform. A bad design decision can haunt the infrastructure during its entire lifetime.

Luca has done a great job addressing the most important design decisions an Architect has to make during the design phase and sharing his vision and advice on the subject. The information he provides on the many components that build your XenApp infrastructure allows Architects to understand the role each component has and make a solid design decision. I also like the style Luca choose, to offer information and suggestions and not mandate the design.

A must read chapter for XenApp infrastructure Architects!

The other four chapters in the book focus on the improvements and optimizations Administrators can check and implement in a production environment. Luca start off by explaining the different monitoring tools you can use to check the performance of your XenApp servers and additional infrastructure components, like the License server and Hypervisors. I like this setup to focus first on getting the right performance counters and then look at ways to improve the performance when required. The book advices Administrators to get to know the XenApp infrastructure and help them to understand what tuning might or might not be effective by providing in-depth explanations for each optimization setting. Not only does the book focus on server performance, it will run you along all components by focusing on session performance, end user experience and WAN connections as well. This covers the entire flow from server to client and checks each contribution to the experienced performance by the end user. Each tool to check the performance is explained in detail, which makes it an even more valuable book to have when you want to focus on XenApp performance improvements.

I for one have added this book to my resource library and expect to use it as a reference quite often when designing and troubleshooting XenApp infrastructures.
4.0 étoiles sur 5 Great book for designing and optmizing XenApp 25 septembre 2013
Par Daniele Tosatto - Publié sur
The book consists of 5 chapters and it starts with design guidelines about XenApp infrastructure: the first chapter introduces you the main elements of a XenApp environment and help you to understand the role each component has and to make the right decision about farm sizing.

Chapter 2 explains you how to monitor XenApp performances and make improvements if needed. In this chapter you will learn how to use some monitoring tools like for example Health Monitoring and Recovery and Performance monitoring counters.
The last 3 chapters gives you details about session startup, user experience and WAN optimizations: starting here you can find useful tips to understand deeply the user logon process and discover potential issues and delays in order to provide the best experience to your XenApp users.

This book has especially been written to provide you with all the information that you need to design a new XenApp infrastructure: for this reason, the book is written for Citrix administrators with knowledge about Citrix XenApp.
The book is about 130 pages so do not expect it is a XenApp Bible!!! It is a guide that helps you make sure your XenApp farm works and performs well.

So, a book well-written that point you on the right direction for designing and optimizing a XenApp infrastructure: a good read if you are considering to became a XenApp architect.
