XenApp and XenDesktop Component Architecture Poster


Focusing on XenApp and XenDesktop for many years, I hear certain questions over and over again:

  • Do you have an conceptual architecture drawing for a XenApp and XenDesktop on-premises deployment?
  • How about a hybrid-cloud deployment?
  • What about the XenApp and XenDesktop Service in Citrix Cloud?
  • What does the logon/app enumeration flow look like?
  • What network ports do I need?

I’ve seen separate diagrams answering these questions, but they are usually buried in an appendix of a very long paper. I thought it would be nice to have a single source for this technical information, which is why I created the XenApp and XenDesktop Component Architecture Poster (PDF File)

Do you like?

And I’m already anticipating your next question: Can we have the source Visio file?

Of course! I just added them to the Citrix Workspace Visio Stencil.

Citrix VDI Handbook for XenApp and XenDesktop 7.15


Almost one year ago, I announced the availability of the Citrix VDI Best Practices Handbook for XenApp and XenDesktop 7.6 (that’s a really long title).

Since then, I received many positive comments from many of you. Thank you.

One of the goals I set was to release an updated version of the handbook for upcoming Long Term Service Releases (LTSR). And with the release of XenApp and XenDesktop 7.15 LTSR, I’m happy to say that we achieved this goal.

Matthew Brooks, Jeff Qiu and I updated the handbook to include new capabilities and recommendations. We added 30 new sections and updated 15 other sections. For example, we have content related to

  1. Cloud
  2. App Layering
  3. Windows 2016
  4. Local Host Cache
  5. Machine Creation Services
  6. Provisioning Services Accelerator
  7. Adaptive Display & Adaptive Transport
  8. And much, much, much, much, much more

A complete list of updates can be found at the end of the paper in the Revisions Table.

So grab a drink, find a comfy chair, sit back, relax and enjoy the Citrix XenApp and XenDesktop 7.15 VDI Best Practices Handbook.

Sync the Windows 10 Start Menu in VDI


NOTE: This is for Windows 10 builds before 1703.  Windows 10 1703 changes the storage location for the Start Menu. Learn more here

Windows 10 VDI. Of course it works. But one of the annoying things that really bothers me is not being able to customize my start menu.

My IT team created a standard start menu. It has 3 browsers, Paint.net, Notepad, Windows Media Player, plus much more stuff I never use.  I really, really, really want to customize this thing

So why can’t we roam the start menu between VDI sessions? Continue reading Sync the Windows 10 Start Menu in VDI

XenServer PVS Accelerator Sizing – Part 2


As you might have read, I recently ran a few XenServer PVS Accelerator tests to determine a starting point for the cache size.  This initial investigation looked at Windows 10 and Windows 2012R2 for boot and logon operations.

Looking back, I determined that I want to include three additional items

  1. Impact of a larger cache size – Increase from 2GB to 4GB RAM cache
  2. Impact of applications
  3. Impact of Windows 2016

Before I get into the results, let me explain the graphs.

  • The blue, green and orange line denotes boot, logon and steady state operations. The first time those colors appear depicts the first VM; the second time the colors appear depicts the second VM. These colors are linked to the axis on the right showing percent of cache used.
  • The solid red area graph depicts the amount of network traffic sent from the Provisioning Services server to the host.  The line should initially be large and then diminish as the cache is used. It is linked to the left axis with bytes per second.

With that understanding out of the way, let’s look at the results.

How does Workspace Environment Management Improve Windows Logon Time


I’ve been able to experience the results of implementing Workspace Environment Management into a Citrix XenApp and XenDesktop environment.  I was easily able to obtain at least a 50% reduction in logon duration.

I understand the why.

I want to now understand the how.

Let’s first examine the Windows logon process.

Your network is hurting your application experience


A few times a year I get addicted to Xbox. Once the kids go to sleep, I can easily spend hours playing Mass Effect, Fallout or Assassin’s Creed.

The games are wonderful and immersive, which is why I spent over 100 hours playing Fallout 3 and another 100+ hours in Fallout New Vegas.  Unfortunately, I’ve experienced some annoying things with these games.  I’ll be in one of the final battles of Mass Effect 3 against the Reapers when the game starts stuttering.  Do you know how hard it is to aim when the system stutters?

Game stuttering, system stuttering or application stuttering is a great way to severely hurt the user experience. How can we reduce app stutters? We need to look at the underlying reason for the stuttering and figure out how to correct.

Network latency and packet loss is a big reason why users might experience stuttering in an application. If a packet gets lost or a packet times out due to high latency, that packet must be retransmitted.  Retransmissions take time. And if you experience a lot of retransmissions, you experience a lot of application stutters.

We’ve already seen how Citrix’s Adaptive Transport impacts

  1. File Copying
  2. Video Viewing

But what does it do to the application experience? See for yourself
