Testing Citrix Published Applications is easy with Login VSI
Hey there Login VSI fans. We are excited to release a new feature in Login VSI 4.1.7 for testing Citrix Published Applications with XenApp. We’ve been able to support Citrix XenApp for some time with some help from our professional services team, but now our default workloads are supported as hosted applications without the need for a published desktop or virtual desktop infrastructure (VDI) as the target. Of course we still provide support for any of your business critical applications you’d like to add to the workloads, and this new release makes that even easier.
So why is this important? Well, because isn’t performance important?
You can read in a number of forums where a virtualization administrator is getting reports of the published applications running slower than when they are executed via the published desktop. There are a number of contributing factors that can lead to this, as well as a number of server-side configuration settings to help improve that performance. Perhaps you’ve read some of these in seamless configuration documents published by Citrix. What makes our new feature so cool is that you don’t have to leave it to your end-users to tell you if the configuration settings you are making are actually improving their experience… you can just use Login VSI to see how these configuration settings affect VSImax. Now you can know if seamless configuration settings like “WORKER WAIT INTERVAL” will work for you end-users at scale.
For those of you familiar with Login VSI, let’s take you through a few of the updates.
First, there are changes to the “Test Setup” section of the management console. As you can see below configuring Login VSI for Citrix XenApp is as easy as changing the mode to “Published applications,” which will change the context to workloads that have been developed specifically in support of Published Applications.

Now that you are setting up the proper workloads the next important consideration is how we connect to the session from the Login VSI Launcher. The important part of this is to setup a specific connection string that is executed via command line—and we help you figure out exactly what that connection string needs to be through our Connection Wizard. Here are a few screens that show some of the options:

Figure 3 - Setting the display size for the session (it’s all optional)
Figure 4 - Other optional configuration parameters
There are many ways to configure your RDSH farms to support Published Apps. Multiple application silos are not a problem and are fully supported. The Login VSI engine will run in each windows session created by a particular Login VSI test user, and the engines will synchronize with each other during the test. This engine will go through a discovery phase prior to starting the test, and during this phase it will identify the application silos and session sharing opportunities that exists in the Citrix environment. These results will then be used during the test.
In order to make the test experience as smooth as possible we have also updated our group policy settings, so make sure to update them if you already have VSI installed.

What to expect
Like yourselves, we were curious to see some of the performance differences between published desktops and published applications. When using the same hardware for the particular XenApp 7.6 servers we saw a VSImax performance increase of 10%. This difference between Published App and VDI testing could be attributed to the lower impact that a published app session has on the XenApp server compared to a published XenApp desktop session. There are several windows processes that do not have to run with a published app (compared to a published Desktop), such as explorer.exe.
Your feedback is important
As with anything we do here at Login VSI, we’d love your feedback after you’ve had an opportunity to try it out. We are always looking for ways to make our products easier to use and for the results of the tests to be more meaningful and insightful to you.
