EUC Score Test Results

Test Results Collected from EUC Score Experiments

EUC Score experiments are designed to measures and quantifies perceived end-user experience in remote applications and digital workplaces, both on premises and in the cloud. This is the landing page leading to different examples and categories of EUC Score test results obtained in community-driven experiments.

IMPORTANT: All test results provided here represent snapshots in time. This means they must always be viewed in the context of the test date, the host infrastructure used, the connected client device, and the versions of all remote Windows desktop software components and remoting protocols involved. The EUC Score methodology employed allows for the reproduction of test runs in comparable test environments at the time of testing. At a later date, however, test results obtained under similar conditions may differ significantly due to newer versions of the components used.

Listed below are selected test results organized in chronological order. They are only a small subset of many data sets collected during a range of community-driven experiments, but they can give you a good impression of the EUC Score capabilities.

 

2025

Test Periods Links Descriptions
Nov 2025 Performance of Citrix on Azure Benchmarking Citrix HDX on an Azure VM with two view modes:
  1. Single View: Measure the impact of extreme network conditions on the Citrix HDX protocol.
  2. Side-by-Side View: Compare Citrix HDX and Microsoft SxS RDP under different network conditions.
Oct/Nov 2025 Dizzion Cloud PC Benchmarking Dizzion Frame Remoting Protocol with three test goals:
  1. Measure the impact of network packet loss, network round trip time and network bandwidth on the Dizzion FRP protocol.
  2. Compare a Dizzion Cloud PC and a Microsoft Remote Desktop (Classic RDP) under different network conditions.
  3. Compare a Dizzion Cloud PC and a Citrix Cloud PC (Windows 365) under different network conditions.
Jul 2025 Windows 365 Performance Show the performance impact that different network conditions have on a SxS RDP session connected to a Windows 365 VM with 8 vCPUs and no GPU. The reference on the left (yellow) side is always 100mbps bandwidth, 10ms latency, 0% packet loss. The network conditions on the right-hand side (red) are constrained by either an 8 Mbps bandwidth limit, a latency of 110 ms, or a packet loss rate of 2%.

Oct 2024 Windows 365 GPU Performance Show the performance impact that different network conditions have on Windows 365 Enterprise GPU Super VMs. Compare RDP connections to an Azure VM with NVIDIA A10-12Q vGPU under unconstrained network conditions versus low bandwidth, high latency and high packet loss conditions.
Mar 2024 RDP vs HDX on Windows 365 Compare Windows remote desktop connections established via the Microsoft RDP and Citrix HDX protocols. The System Under Test (SUT) is a "minimal" Windows 365 Enterprise VM with 2 vCPUs and 8GB of memory, hosted on Azure West Europe.
Jan 2024 Parallels RAS 19 Protocol Extensions Benchmarking Parallels RAS 19 Extensions with two test goals:
  1. Analyze how much Parallels RAS Accelerated File Redirection speeds up the mapping of local files and folders in RDS and AVD desktops.
  2. Investigate the performance benefits of Parallels RAS Universal Printing when compared to Remote Desktop Easy Print as built into RDS and AVD.
Jan 2024 FSLogix Profiles on Azure Compare FSLogix stored on Azure Files versus Azure NetApp Files, both on identical Azure VM types and monitored with ControlUp.

2023

Test Periods Links Descriptions
Oct 2023 VMware TestDrive VM Performance Benchmarking different aspects of VMware Horizon and the Blast protocol on VMware TestDrive with three test goals:
  1. Explore the the difference between a Blast connection to a VMware TestDrive VM with NVIDIA L40-2Q GPU versus a VM without GPU.
  2. Analyze the difference between a high-latency Blast connection versus a high-latency PCoIP connection to a VMware TestDrive VM with an NVIDIA L40-2Q GPU partition.
  3. Compare a high-latency Blast connection from the full Horizon client with a high-latency Blast connection from a Chrome browser ("Web Blast").
Jan/Feb 2023 Frame Remoting Protocol Analyzing Dizzion Frame Desktop as a Service and Cloud PC performance on three hyperscalers:
  1. Microsoft Azure: Compare an RDP session on a physical Windows workstation to Frame Remoting Protocol (FRP) connections to Windows VMs with GPU.
  2. Amazon Workspaces: Compare an RDP session on a physical Windows workstation to Frame Remoting Protocol (FRP) connections to Windows VMs with GPU.
  3. Google Cloud Platform: Compare an RDP session on a physical Windows workstation to Frame Remoting Protocol (FRP) connections to Windows VMs with GPU.
Jan 2023 Thin Client Performance Testing thin client devices under five different conditions:
  1. Explore the difference between a remote connection from a thin client to an AVD session with a remote connection from the Windows reference client NUC2 to the local reference host PC Lancelot.
  2. Compare the performance of different thin client types under IGEL OS 11.8 when connected to an Azure Virtual Desktop session.
  3. Compare the performance when connecting to an entry-level Windows 365 Cloud PC from a Windows client or from a thin client.
  4. Find out how good a remote connection is over Frame Remoting Protocol (FRP) from the Chromium browser of a thin client under IGEL OS 11.8.
  5. Find out what the performance impact is on an Azure VM connection over Frame FRP from a Chromium browser in IGEL OS 11.8 when the assignment of the client GPU didn't work.

How it works

EUC Score test results are visualized in the HTML5 Sync Player that runs inside a browser, such as Google Chrome or Microsoft Edge. The Sync Player client area is divided into two foreground media output tiles at the top, a numerical data visualization area at the bottom, and a control and status bar in the footer. The horizontal bar at the top of a screen video tile contains a title on the left and two icons on the right side. A click on the first icon opens a popup with setup details. A click on the second icon zooms into the screen video. A click on the Report button in the bottom right corner of the footer opens an overlay dialog in the data visualization area, showing test observations and findings.

In Single View Mode, the top left tile contains a test run screen video and the top right tile shows animated text representing timely correlated user activities and session runtime details. The numerical data visualization area shows animated telemetry data collected on the host side.

In Double View Mode or Side-by-Side View Mode, both top tiles include test run screen videos with a yellow border on the left side and a red border on the right side. The numerical data visualization area shows animated telemetry data collected on the host side that is color-coded according to the video border colors.
