How Using a Virtual User can Quantify the Performance of SAP and Citrix

When interacting with enterprise applications, the user experience is important.

Users must be able to smoothly and efficiently interact with the application to be productive and achieve the goals of the enterprise. The applications are expected to be responsive, dependable, and consistent in their presentation.

Over the last few years, I’ve published many articles and held many presentations on sizing and scalability of virtual desktop environments and while I’m confident there are many more to follow, today I’d like to show you something new: A continuity and performance test of a business-critical application.

Earlier this year the SAP Co-Innovation Lab (COIL) and Citrix asked if we could help them illustrate the continuous performance of running a GEO-dispersed, local and remote end-user connectivity to SAP S/4HANA; delivered by Citrix Virtual Apps and Desktops (CVAD) through Citrix Cloud. The hypothesis was that having a CVAD server as close as possible to the SAP backend would outperform remote connections coming in via a traditional VPN. However to validate this, a continuous load with virtual users was required.

Using Login PI, together with engineers from Citrix, we designed a user-workload that would resemble mission-critical actions for any SAP user (e.g. starting the application, authentication, and working through a financial ledger). Login PI allows you to quickly create these workloads using the drag-and-drop application x-ray. Below you will find an example video of the final workload.



Generating workload and being able to get an alert when performance degraded was only the start of this project. Login PI also allows you to track the performance of an application in detail; we call this deep application testing. During the tests, we collected some screenshots that clearly show that the performance of an environment can fluctuate over time, whilst the user performs the same actions.

It quickly became clear that CVAD was outperforming traditional VPN, especially in the locations furthest away from the datacenter, as network latency can have a major impact on the execution time of user requests. We’ve also learned that network latency can sometimes be unpredictable, as the route it takes may vary.
