I have an old system, Xeon proc, 6 core, 3.5 GHz, 32GB ECC Ram. Running Mint LMDE 20/Mate. System has never run Windows. System on SDD and VM's across 2 other SDD's. Backups go to spinny-go-rounds with mirror RAID. I think it is more important to have VM's on SSD than the host system. Swap is on SSD but I set swappiness to 0 so it only swaps if it has to. This does not prevent swapping like some people think. Doesn't seem to make that much difference anymore, used to way back when.
Don't let AV programs mess with your VM files while you are running. I don't let the network start on boot up, slows things down when all the Windows stuff phones home. I turn it on when I want to use it. If you run Windows Defender, disable shared folders until you need them. It panicked when I downloaded a new version of the Sonicwall client to my Linux host download folder. Not sure if it scans mapped drives or not. I don't leave them active. Windows tends to be a bully, I guess that is good along with being annoying.
I run (mostly) 2 W10 VM's at the same time and usually 1 or 2 Linux VM's. The W10 VM's are on different drives. The W10 I use for development has 6 GB Ram, 1 Proc, 3 cores. This seems to help Visual Studio and SQL server (light) which are resource hungry. I am doing some work with netcore and Blazor Server which is also resource hungry. I seemed to get a big improvement going from 1 core to 2, less so to 3 and 4 seemed a waste. Without Visual Studio, I would probably run that system with 1 or 2 cores. The Linux VM's are all 1 core, 2GB. I rarely see any hiccups, performance is suitable for me. Can't compare to native, don't have a Windows system other than a surveillance camera system (W7).
My Raspberry Pi runs dotnet core. It is slow.
My way is "a" way, but maybe not the best way. Have a good one.
