I am running a Hyper-V Server 2019 (Core) on a Gigabyte AMD X570 Mainboard using a NVME SSD Corsair Force MP600. The mainboard does not really have drivers for Windows Server, but I did migrate all missing drivers from a W10 machine with the same hardware. All is working, but the disk-speed 4k blocks is very bad when disabling cache. As I am using Starwind vSAN, I cannot use the disk cache.
Using this command:
[login to view URL] -c100G -t12 -si -b4K -d30 -L -o16 -w40 -D -h c:\[login to view URL]
Result 9MB/s writing, 13MB/s reading
Another machine with the same hardware, but W10 brings 400/600 as a result.
How can I speed it up?
