Poor 2022 VM Performance.
I have a HP DL320 G6 | Xeon E5630 | 96GB RAM | [4] 1TB HDDs, RAID 5 - all | Windows Server 2022 Datacenter. I am running two VMs on it for various services like Unifi, FM audit, Bell software, etc. Both VMs are very sluggish. Currently, I have shut one down, moved VM2 from 2 CPUs to 3, and assigned 24GB RAM. Doesn't make any difference, still incredibly sluggish. Doesn't matter if I'm using on the host or over remote desktop on another PC. I've repurposed old hardware like this before without issues. Looking at the CPU usage of the host, you'd think everything would be OK. Is there something I'm missing on configuration? Is there something that needs to be disabled in 2022? Or should I scrap this server and get a new one? Thank you for your input.
For the host OS with that hardware Ubuntu 18 might run better with virtualbox.
UniFi will run just fine with 1vCPU and 2GB ram.
Sort by Response Time. What's the highest?
Repeat for the guest.
Please post a snip as above from both host and guest.

RAID 10 won't make much of a difference over the RAID 5 as far as it being noticeable.
If you can find a couple more drives if the server will handle it, go that direction. Or, there are Intel Enterprise SSD options on auction sites that could be set up in a RAID 1 pair to put your higher IOPS needs workloads on. They are not that expensive and most have a lot of wear left on them.
We did that with a lot of 3-4 year old laptops that had spindles in them. Once the SSDs went in folks thought they were new. The cost benefit was another 2-3 years of life out of them so long as the user didn't kill the laptop.
There were generally ONLY fitted to performance models, and optional extras!
4 x 1TB HDD in RAID 5, is not many spindles and therefore IOPS is low.
Are these SATA, 7,200 rpm or slower ?
Do you have a HP Smart Controller fitted with BBWC (battery backed write cache) or similar ?
Considering age, noise and power, I would consider cheaper low power alternatives, unless you are looking for cheap cheap cheap!
FYI, we scrap G6s ! Yes we through them out in the skip !
As for Unfi Controller, better running it on a Raspberry Pi !
