The Logon VSI test results for this environment demonstrate that it is well balanced and that it performed well. The environment as configured will support more than 500 users. The ability to scale up while ensuring a good user experience is a function of the capacity of each part of the stack. If any part of the configuration is undersized for the workload, latency will spike and the VDI user experience will degrade.
As the active user count increases in a VDI environment, eventually a bottleneck will be encountered somewhere in the overall design that will cause latency to spike. Alleviating spikes in latency at scale might require remediation steps when a bottleneck is identified:
