noVNC is working very slow

[NV.Kormiltcev]

Hi everyone!
Who can help me with configuration in novnc?
So, i can't normal use gui interface because i always see lags.
If somebody know how to integrate spicy-html5 in proxmox, i will be very grateful!!!

hi

what's the connection between you and the pve server? (bandwidth/latency?)
if novnc is not fast for you, my guess is that spice will also not be much faster

while integrating spice-html5 is not trivial, here are some general Development pointers:
https://git.proxmox.com/
https://pve.proxmox.com/wiki/Developer_Documentation

most of the gui is the 'pve-manager' repository:
https://git.proxmox.com/?p=pve-manager.git;a=summary

i use 10gbit/s(local network)
I want that my novnc will work approximatelly as rdp. Pls see my attach novnc.gif.
My mouse coursor move very slow.

there is no gif attached to our post...

also vnc will never works as fast as rdp, because vnc in qemu sits outside the guest os and has to send images over the network, while rdp has knowledge about window position/layout etc.
(also rdp supports h264 encoding, which vnc does not)

How i can make faster?
Maybe i can install some addition programs or?

from your gif i cannot really see any "slowness" (i believe that there is though)
vnc performance is limited by:
server cpu, network bandwidth/latency, client cpu

there is not really anything you can do to speed it up software wise
did you try spice already? that should be a better experience

yes spice is faster, that i dont know how to use spice-html5 instead of novnc

as i said, integrating spice-html5 is not trivial

first i'd check where the bottleneck really is: check the cpu usage on the server/client, check the bandwidth used
