Hello everyone,

My testing Config :

- AMD Ryzen 1600X
- Asus Prime AB 350 Plus
- 4 x 8Go Crucial 2400Mhz
- 4 x MX500 Crucial 250Go in Raidz1 (/root & VM-Images only)
- 2 x 4To in raidz1 (vzdump, backup & ISO storage)
- Dual NIC 1Gbps

No general performance problem on the side of the Proxmox when VM is launched but I have an RDP problem on my Guest VM WIN10. The problem is graphic. The VM has no worries about RAM, CPU consumption and I do not see an IO Delay on the hypervisor side.

Yet in RDP (local or remote) windows take time to shrink, windows leave a drag during their reduction etc... The RDP tool is however set to have maximum quality.

The VM WIN10 :
- Windows 10
- Updates OK
- Drivers : VIRTio scsi, balloning, NetKVM, Qemu-Guest-Agent.
(Despite the fact that the service runs on the VM I have no information displayed in the summary of the VM under Proxmox ... yet Get-Service QEMU-GA tells me that it works and a qm agent VMID ping me back nothing so everything should be ok but i have no information.)

If you have any suggest ?

For information on the same machine with other pool of SSD & HDD (same model and size) on Citrix I have no problem for RDP etc... (fucking licence cost haha)
 
Hello,

May i ask what is the screen resolution you are using client side ? and what kind of RDP client is used too ?

Best regards,
 
Tested with official MS RDP Client and via Remmina+freerdp plugin. Both gived the same result = poor performance and grapghical issue...

And again both tools works fine on Xen VM =(

For the resolution : 800x600 / 1280x720 / 1920x1080 / 2560x1440
 
I have not tested with Iperf but I use 100% NIC 1GB when transferring the VM to the shared folders of my hypervisor. I can also use 100% of the internet connection from my VM. It's only the RDP itself that displays a horrible rendering ...

Do you still prefer a test via Iperf?
 
I guess transferring to the hypervisor is not quite the same as loading the guest. As RDP is very sensitive to network conditions variations, i suppose clearing out that client ==> VM is ok might help.
 
I have already try to create a new VM with different settings for the same experience trough RDP.

VM To HOST in file

Result are suffisant to make a good rdp I think =(

Ok get it : Client is also a VM => Server is a Win 10 VM : RDP from client to Win 10 is a disaster.
I just fired up a WIN10 VM , stock, no updates, no drivers... runs mostly smooth on 2560x1600 connecting from my laptop to the guest.
 
From my client in local I have full speed an from remote to.

The problem isn't network speed ;-)
