VM console issues on Truenas Scale


I am using Truenas Scale 23.10.2, and have been struggling with very slow user experience when I use the console to my Ubuntu Desktop which runs as a VM on Scale.
It is extremely slow most of the time. If I shall click on a icon in OS or a new tab in chrome it might take up to 10 seconds before anything happens. The same can be when I am typing.

Some times everything works nearly OK, but for the most part it is very sluggish.

Any other experienced this and have a solution? I didn’t experience this with 22 version of Scale if I remember correctly and it came with 23 version.

Thank you!
