Sizing Windows 2016, Windows 2012 and Windows 10 Virtual Machines


It has been almost one year since Windows Server 2016 was released at Microsoft Ignite. Are the virtual machine sizing recommendations for Windows Server 2012R2 applicable to Windows Server 2016? And since we are talking about sizing virtual machines for XenApp and XenDesktop, it might be a good time to revisit Windows 10.

Let’s first look at virtual CPU allocation recommendations: Continue reading “Sizing Windows 2016, Windows 2012 and Windows 10 Virtual Machines”

Microsoft Office 2016 Impact on XenDesktop Scalability


A day doesn’t go by when I don’t open up at least one Microsoft Office application.  Even on weekends, when I’m not working, I usually open at least one application. It should be of little surprise that Microsoft Office is one of the most used set of applications in many RDS/VDI deployments. But what impact does Microsoft Office have on overall single server scalability? How does the impact change as we move users from Office 2010 to 2013 and onto 2016? As you can see, single server density decreases. Office 2010 gives us the best scalability. Office 2013 reduces single … Continue reading Microsoft Office 2016 Impact on XenDesktop Scalability

XenDesktop 7.7 and Windows 10


The other day, I was able to share the latest single server density results when running Windows 7 on XenDesktop 7.7. We looked at a range of parameters like: PVS vs MCS PVS Disk Cache vs RAM Cache Citrix Policies: Very High Definition vs High Server Scalability vs Optimized for WAN Windows 7 optimizations Once that testing was complete, we moved onto the next version… Windows 10. An again, looking at the exact same parameters. First, we look at Microsoft Hyper-V 2012R2 Second, we look at Citrix XenServer 6.5 SP1 What do you notice? Between XenServer & Hyper-V… Not much … Continue reading XenDesktop 7.7 and Windows 10

XenDesktop 7.7 and Windows 7


We recently completed a massive round of testing looking at many of the different deployment configurations we can do with a Windows 7 desktop in XenDesktop 7.7. We wanted to look at how different factors might impact single server scalability. PVS vs MCS PVS Disk Cache vs RAM Cache Citrix Policies: Very High Definition vs High Server Scalability vs Optimized for WAN Windows 7 optimizations Each test was conducted utilizing the same, knowledge worker workload.   As you see, each test builds upon the previous test while only modifying a single parameter. As I’ve gone through the initial results, some … Continue reading XenDesktop 7.7 and Windows 7

Windows 10 Optimization: Part 8 – The Results


Statistics are fun. It is amazing what interesting insights you can get from statistics. For example About 20% of workers would work harder if their employer offered a $1,000 shopping spree at the store of their choice – You hear that Citrix! About 20% of the people who watch the Super Bowl do so for football, the rest watch commercials About 20% of copy machine issues worldwide are caused by people sitting on them – That is awesome Over the past year, my blogs are 20% funnier And my absolute favorite statistic is from Homer Simpson (who else): People can … Continue reading Windows 10 Optimization: Part 8 – The Results

Windows 10 Optimization – Part 7: ICA


Were you planning to buy that? Nope. Of course, as you saw in my previous blog, my stupid lawn mower wheel snapped off with only 30 minutes left in the season! D’oh! Figured I would just head to the local hardware store and buy a new one. Guess what? Hardware stores in Minnesota don’t sell lawn mowers in late October. I guess no one wants to mow snow, although it might look cool. I went home, got online and eventually ordered a new mower, which happened to be battery-powered. I still can’t believe I did it, but here is why: … Continue reading Windows 10 Optimization – Part 7: ICA
