Console novnc slow

[Xing]

Hello Community Proxmox,

i have problem on promox 6.3-4, on this cluster i have 19 nodes and total 308 VMs .

i have problem that when i use noVNC for console vm , i have problem on slow moving inside console cursor. having spike or lag on it.

i use CPU E5-2667v2 and all nodes performance on CPU running not above 30% RAM not more than 70% Disk all pure SSD SATA lll write read speed 500mb/s

Network Internal 10Gbps on all nodes.


i'm not sure what cause of lag on console in noVNC.

In general, the noVNC is slower than SPICE [0] or VNC [1], however, to narrow down the issue, can you test SPICE/VNC on a VM to see if the issue is a general issue in your cluster?
