No Hope for Slow noVNC Console Access??

Hey all,

I'm fairly new to ProxMox, (within the last year and half) and one thing that is about to become a big deciding factor on whether I use it at my office or with clients is the noVNC access and ridiculous slowness in that console. I have read numerous other threads that noVNC is the root cause of the issue as I'm running 14th gen Dell servers with 192gb+ ram and 20+ core CPU's. So the available hardware isn't the issue.

This issue seems to focus around Windows VM's the most, Linux VM's not as bad. But the lag and slowness is so bad in Windows that I'm about ready to drop consideration for ProxMox in favor of VMware. What specifically I notice is that when I type a password into a Windows VM, it is so slow/laggy the password never gets entered correctly unless I slowly type each character, wait 1-2 seconds, then type the next character. To me that seems a bit unacceptable.

The other but less annoying issue is the mouse movements being extremely slow and laggy, to the point it makes navigating with a mouse time consuming and tedious just to open the correct menu's.

I have yet to get SPICE console to work, but I feel like a third part separate downloadable item is just one extra thing to be aware of and download regularly just to keep accessing the SPICE console. I wish either the noVNC console was just faster or if Spice had native html5 type of built in web client.

Am I missing something? Are the noVNC issues of this same mentality from 2017-2021 been fixed?

Help!
 
There are a few existing posts on this forum related to this issue, maybe they are useful to you:

SPICE is relatively simple to configure (depending on the guest os), so I would recommend you give it a try. While spice-html5 is not integrated into Proxmox VE, clicking the console button when SPICE is available triggers the download of the file which can then simply be opened in virtviewer.
