Parallels RAS 19 HTML5 versus Full Client

Testable question: Is there a noticeable difference between the Parallels RAS 19 HTML5 client and the full client?

 

	Simload and Link	View and Type	Observation
	SL1-ChromeFishbowlHTML5	SxS View - Standard	Slightly better performance with HTML5 client at almost identical network consumption.
	SL1-MSEdgeVideoConf6	SxS View - Standard	Higher network consumption with HTML5 client and higher CPU load with full client.
	SL1-WMPlayer720pMP4	SxS View - Standard	Higher network consumption with HTML5 client and higher CPU load with full client.
	SL1-RollercoasterDX9	SxS View - Standard	Slightly higher network consumption with HTML5 client.

Result: The performance of the Parallels RAS HTML5 client and the full client are almost identical.

Azure VM with Parallels RAS 19

Testable question: What are the results when running the score Simloads (type 3) on an Azure D4s v3 VM with Parallels RAS 19?

System under test: Azure West Europe, D4s v3 VM, Windows Server 2019 Datacenter, Xeon Platinum 8272CL 2.60GHz 4vCPUs, 16GB RAM, 32GB Premium SSD P15.

Connection: RDP-UDP, 14ms round trip time.

 

	Simload and Link	View and Type	Observation
	SL3-AppStart	Single View - Standard	APP LAUNCH SCORE = 0.61
	SL3-AppDialog	Single View - Standard	APP DIALOG SCORE = 0.31
	SL3-FractalsDragon	Single View - Standard	FRACTALS DRAGON SCORE = 2.63
	SL3-FractalsPythagoras	Single View - Standard	FRACTALS PYTHAGORAS SCORE = 4.38
	SL3-GDIPlusRect	Single View - Standard	GDI+ RECTANGLES SCORE = 2.35
	SL3-IOPS	Single View - Standard	IOPS SCORE = 9.87

Result: The Simload type-3 scores are in the range as can be expected on an Azure D4s v3 VM, independently of Parallels RAS 19. Start times and CPU performance is good, while the Standard SSD IOPS performance of the VM is below average.

Windows 365 Cloud PC versus Parallels RAS 19 Full Client

Testable question: What is the difference between a Windows 365 Cloud PC and an Azure D4s v3 VM with RAS 19?

 

	Simload and Link	View and Type	Observation
	SL3-IOPS	SxS View - Standard	CPC IOPS SCORE = 15.18 | RAS19 IOPS SCORE = 9.87. The storage in the RAS19 session performs significantly better.
	SL1-ChromeAquariumWebGL	SxS View - Standard	RAS19 session shows faster load time and better performance. CPUs are at their load limits on both sides, but CPU queue length in the Cloup PC session is much higher.
	SL1-ChromePhotoGalleryJS	SxS View - Standard	CPU comes to its limits on CPC side. Higher network bandwidth and better user experience in the RAS19 session, in particular during image transitions.
	SL1-MSOPptSimple	SxS View - Standard	Almost identical user experience, but initially CPU load is significantly higher on the CPC side.
	SL1-WMPlayer1080pMP4	SxS View - Standard	Video doesn't start in the CPC session. Spectacular video artifacts on the RAS19 side. Both is unacceptable for users.

Result: The Windows 365 Cloud PC cannot keep up with the Azure D4s v3 VM with Parallels RAS 19. This doesn't come as a big surprise due to the different numbers of vCPUs.

NUC2 Physical Machine versus Parallels RAS 19 Full Client

Testable question: What is the difference between the physical NUC2 reference PC and an Azure D4s v3 VM with RAS 19?

 

	Simload and Link	View and Type	Observation
	SL3-GDIPlusRect	SxS View - Standard	NUC2 GDI+ RECTANGLES SCORE = 1.3 | RAS19 GDI+ RECTANGLES SCORE = 2.35
	SL3-IOPS	SxS View - Standard	NUC2 IOPS SCORE = 3.04 (local SSD) | RAS19 IOPS SCORE = 9.87 (Azure Premium SSD P15)
	SL1-BSPBlendingDX11	SxS View - Standard	The physical NUC has a GPU, allowing it to offload DirectX functions. This results in lower CPU load and much better performance. The Azure VM without GPU cannot keep up, response to user input is affected massively.
	SL1-MSEdgeCarVisualizer	SxS View - Standard	The physical NUC with a GPU massively outperforms the Azure VM without GPU.

Result: This test setup is absolutely unfair, but some customers were asking for exactly such a comparison! The physical NUC2 reference PC with its embedded AMD GPU and the Samsung SSD massively outperforms the Azure D4s v3 VM with RAS 19.
