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.

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

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
What do you think about that?
