Hello, As far as I know, spice doesn't support GPU acceleration on the host. Its CPU only. The vGPU option in the host configuration only works for specific enterprise grade GPUs. At least in my experience, spice performance is limited by three different parameters: A. Bandwidth. B. Network latency. C. Host CPU utilization. BTW, I just fired up ~20 virt-viewer windows, ~1/3 of them GUI w/ 2K resolution, over a 10GbE link and performance was OK, and network utilization was well below 1GbE. - Gilboa On Mon, Jan 11, 2021 at 10:00 AM <ozmen62@hotmail.com> wrote:
Thanks for all, Clients have 1Gb and iperf3 results are 900Mb per client, if multiple client run at same time. I think client and server network is ok.
I've figured out something else. On Host setting there is an option for "console and gpu". separated or consolidated. It's made me suspected that the issue might come from this.
I've checked my gpu which is onboard
lshw -C Display *-display description: VGA compatible controller product: MGA G200eH3 vendor: Matrox Electronics Systems Ltd. physical id: 0.1 bus info: pci@0000:01:00.1 logical name: /dev/fb0 version: 02 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom fb configuration: depth=32 driver=mgag200 latency=0 resolution=1024,768 resources: irq:17 memory:d8000000-d8ffffff memory:d9b98000-d9b9bfff memory:d9000000-d97fffff memory:c0000-dffff
Spice uses gpu, RDP uses cpu. So, maybe if i change my primary gpu with some powerful one it can effect spice in a good way
