Hi Murilo, Have you tested/compared VNC based traffic between CloudStack VMs and proxmox (or others) from the same server and client locations?
Depending on your env, if you've a busy console proxy you can try to upgrade the systemvm (CPVM) offering with more CPU (cores and speed) and look at the network setup. You could also explore alternatives, for example if the guest VMs have RDP setup/install such as in case of Windows VMs, you could use a RDP client such as the Microsoft remote desktop app on the client side. In my experience, RDP client with guest VMs have better performance and I/O (webcam, microphone, speaker) than compared with VNC (noVNC).

For virtual machines with desktop enabled, the performance of the noVNC console is very low. I came from experience with Proxmox and in it the noVNC console, even protected by SSL, is much superior. That's why I wondered if there was any way of tuning noVNC in ACS.
