[Tuning / XenApp 6.5 + AppCenter] In the localized console with the Load Evaluator


If you are using the french version of AppCenter, you have probably encoutered a little issue while assigning a load evaluator.


Suppose you want to use the built-in Load Evaluator ‘Advanced’.

When you create the new and assign the name of the Load Evaluator, if you write it with its name ‘Avancé’, instead of search it in the list ‘Calculateur de charge’, the affected servers will report a load index of 10,000 (full load), even if no users are using ressources on these XenApp servers.  read more

[VDI] POC for Citrix XenDesktop 4 and HDX 3D (part 1/4)


The purpose of this post is to present a feedback on a pilot project based on Citrix HDX 3D and XenDesktop 4 I have achieved for a great company. The study is presented in 4 parts:

  • Part 1 : Scope of the POC and required architecture
  • Part 2 : Installation of Server Components
  • Part 3 : Installation of Components for Blade PC
  • Part 4 : Results

Scope of the POC

The justification of the POC is to validate the functional and performance aspects of a business application having to manage huge 3D images.

Out of the scope

Virtual Desktop Provisioning: the aim of the POC is to check the performance capabilities of the Nvidia Quadra graphics chipset. Only after this validation done, that the delivery of  desktop built on Windows 7 x64,HDX 3D and the business application will be industrialized with Virtual Desktop Provisioning. In the context of the POC, the blade PCs are manually installed.

Issues encountered

  • Citrix : version of HDX 3D component compatible with Windows 7 x64
  • NVidia : version of NVidia Quadro Pro driver for Windows 7 x64 and validated by HP on their hardware

Architecture Diagram

All the server components of the Citrix XenDesktop architecture used for the POC have been deployed on a single server.

Components of the POC for XD4 HDX 3D


A complete checklist of components for a POC with XenDesktop 4 can be found at:



  • 1 Gb for the DDC
  • 1 Gb per physical host (hypervisor)
  • 2 Gb per workstation – Vista / Windows 7


  • 1x DDC server – 20 Gb
  • 1x build workstation – 20 Gb


The virtual infrastructure is not at all required in the context of this POC for the business application and 3D. It was anyway chosen because of the choice by the client to the test environment..

Software requirement

  • VMware Environment with version 3.x or later installed and Virtual Center 2.5 or later available

Administrative privilege


  • 1 Gb NIC minimum, dual 1 Gb NICs recommended


Domain Administrator Account

  • Required for the installation of the DDC and initial security configuration

AD Test User Accounts

  • These users have to be placed in a global group, which is referred to as the XD POC Users group.

Dedicated Organizational Unit (OU)

AD Group Policy

  • An Organization Unit (OU) for the XenDesktop POC has to be created. All policy inheritance has to been blocked on that OU.


Software required before setup

Before installing Citrix DDC, all the following components must be installed on the targeted computer, when a all the DDC components has to be deployed on a single server, which is the case of the POC:

  • Microsoft Windows Server 2003 (Standard or Enterprise Edition, with Service Pack 2 installed)
  • Terminal Services running in application mode.
  • Microsoft IIS 6.0 with ASP.Net
  • IE Enhanced Security disabled

Software added (if not present on the operating system) by the setup of Citrix DDC

  • Microsoft .NET Framework, Version 3.5, with Service Pack 1.
  • Java Runtime Environment (JRE) Version 1.5.0_15.

Citrix binaries required for setup

  • DDC_VDA.iso : size of 1 219, the software is delivered as an ISO file by Citrix, so it required to mount the ISO file with a tool as DAEMON Tools or to burn a CD

Computer requirement

  • Memory (RAM) : 768 Mb minimum, 2 Gb recommended
  • Disk space : 20 Gb for OS and installation
  • Network interface : 100 Mb minimum, 1 Gb recommended
  • IP address : static IP address
  • Active directory : must be the member of the domain

In the context of the POC, an evaluation license is used. The license service is installed on the same server as the one hosting the DDC.

Software required

  • Citrix License Server version 11.6.1 to manage the evaluation license


For performance reasons, physical Blade PC with Windows 7 x64 hosting the desktop to deliver to the test users. The VDA is installed on these machines to manage communications and broker connections.

Computer requirement

  • Physical Blade PC

Software requirement

  • Windows 7 US x64
  • Citrix VDA

Endpoint devices retained in this POC are test workstation with Windows VISTA for the XenDesktop Receiver and as a management station for administration. The Desktop Receiver is installed on this workstation along with all the management consoles. The Workstation should have the .Net Framework 3.5 sp1 installed.


IP addresses

  • 1x build workstation IP address
  • 1x DDC server IP address
  • Xx workstation IP addresses; each virtual desktop will need an IP address


  • A separate VLAN for the XenDesktop servers and workstations
  • Switches : disable Spanning Tree or enable Port Fast (STP Fast Link)

[Tuning] IIS Configuration for the Web Interface 5.X



The first connection on a Web Interface 5.x on Windows 2008 has a load time over 5 minutes to display the page of the application publication.


By adding to the ASP file NET.CONFIG the following line

<generatePublisherEvidence enabled= »false »>

and by executing the command :

C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v /Citrix/XenApp

The web interface provides display time of about 5s.
