Citrix: How Network Latency Impacts User Experience


“What is the recommended network latency for a good user experience in an ICA session?” This age-old question comes up all the time, and in true consulting fashion the answer is… it depends.

So, why is that? What does it depend on? Well, first and foremost, it depends on what the user is doing within the session. Given the exact same network conditions, resources, and configuration, the activities taking place within the session could affect the experience. For example, someone who’s checking email, working on Word documents, spreadsheets, etc., could have better perceived performance than someone who’s watching videos. (i.e. the higher the graphic intensity within the session, the higher the perceived degradation could be, and vice versa).

It also depends on who you ask. User experience is a very subjective thing. Different people have different opinions on what constitutes a good user experience. Based on what I’ve seen over the years, different people measure user experience differently. Some people base their opinion solely on what they see whereas others take into account the mechanics of the solution, all the pieces of the puzzle and how each one works, so tend to have a higher tolerance for the perceived performance and are more lenient with their opinions. And you will also have varying opinions within those two groups of people. A tool like Login PI can help in situations like this by proactively monitoring and measuring user experience and helping determine whether there is really an issue within the environment or somewhere between the chair and keyboard.

With that said, the first thing that needs to be addressed is the configuration. Different use cases, and even groups within the same use cases, may require different settings based on what type of activities they need to perform within their session, how far they are from the XenApp servers or VDI desktops hosting their sessions, and the characteristics of their network connection. Therefore, make sure to select the appropriate graphics mode for each scenario.
