Anyone have an idea why Ubuntu is so laggy?

No, just commenting on the reason for the seeming discrepancy in size on disk vs reported size of the files.
Ok, thanks.

vdisks by default are created "sparse". That means only the used space is actually allocated. That is good for some scenarios, bad for others. Good, in that you can present an OS with a large amount of free space to make installers happy, and allow growth without reprovisioning or other manipulation. Bad, in that it can be easy to allocate more than the actual amount of space, causing strange issues when the device is full but the OS in the VM shows plenty of free space. Also, the host file system can get fragmented, causing performance issues with some types of file systems and media.
If you wish to force the file to immediately consume the full size of the vdisk, that can be easily done.
Do you think that is what causing the problem?

Can it be on the graphic card setup. Not able to format a standard web page, not even after 30 sec. When I start LibreOffice, it starts quit ok, but not able to format the screen, see attached file.

Strange. Only 32 GB used on the cache, 3 VM`s is more than 100GB alone. The 3 different VM`s vdisk`s name is the same "vdisk1.img".

What drive is the vdisk located on? Do you have a cache drive? Running VMs with the OS vdisk on a drive in a parity protected array is often slow because of the relatively slow write performance on Unraid.
I run 4 ssd`s in Raid10. Domains is on the cache drive as well as the vdisk file. Is the default vnc driver ok to run?

Hi,
The Ubuntu Desktop I am setting up are very slow and laggy. It`s like its running from a CD-ROM or a corrupt video driver. I think I have allocated enough resourses wit 4GB RAM and 4 cores/8 threads running on Xeon Silver 4116.
I hope anyone can help.
Cheers

Thanks all,
I am up and running now with Plex and VMs. Very much that fast due to SpaceinvaderOne`s very useful instrction videos. Running Plex with Nvidia RTX4000. Soon as data is copied I will do some testing.

Hi,
I am running 4 x 1GB ssd in the cache pool in Raid 1. I want to set it up as Raid 10, and have seen how to. But is it possible to convert from Raid 1 to Raid 10 without deleting whats on the drives?

What are the general recommendation regarding cashe drives? Big as possible? Does many drives change anything? I have up to 4 x 1TB SATA ssd`s. I have 2 x M.2 512GB PCIe ssd`s which I can add on a PCI card.

Hi,
A coming unRaid setup includes 2 x 10GB and 2 x 4GB drives, plus up to 4 x 1GB SSD`s for cache. What would be a good way to arrange the hard drives?
Cheers,

Hi.
I'm new to this forum and new to unRaid. In my late 50`s, not tech skilled. Been in the computer business since mid 80`s, actually launched Amiga 500 for Commodore back in ´87 I think it was.
I am planning setting up UnRaid on a Supermicro Workstation (pressed purchase button today). Plex (4K transcoding) on Unbuntu with GPU passthru, a Mac vm, a Win vm, Roon Server, backup for friends and family, etc. So I will most likely ask for help from time to time.
Looking forward to talk to you.
Cheers,
Frode
