Hello.

At my company we use the proxmox console (noVNC) to view virtual machines for internal use only.
We host a lot of VMs for customers, which they can access through our website in a similar fashion, we also have a "console" button which links to our own noVNC server and opens a browser window of the VM.

Our config is obviously not the same as Proxmox's, with the most notable differences being that we have a bit more visible lag, eg moving a window has a lower update/refresh rate than proxmox. And I cannot find where to deactivate the remote cursor, which adds to the problem of making the lag really obvious.

I did a test on proxmox, our website's console and hosting the noVNC server locally. They all give more or less the same performance when moving a window around, but proxmox is still a tiny bit better. But the conclusion was that hosting the server locally/remotely has no impact on the performance, meaning that our config is just not good enough.

Is there anyway I can see the proxmox noVNC source code or does anyone have any ideas on how to reduce this lag?
We are currently looking into moving away from noVNC if we can't find a solution to this.
If anyone has a suggestion of a different protocol to use, please let me know.

sure, it's publicly available here: https://git.proxmox.com/?p=novnc-pve.git;a=summary
but we do not do anything special besides integrating some proxmox specific features (like the ticket handling etc.)

the only difference i can imagine that could impact performance would be the websocket proxy in use, we use our own implementation in our perl http stack[0]
or rust implementation for the proxmox-backup-server[1]
