Hmm I don't see any problem with the config of the VM.
How do you test it in the Windows VM?
Have you done some benchmarking on an empty VM disk image directly on the PVE host? This way you will know what you can expect from the ZFS pool itself.
Doing it with direct and sync enabled and with a block size of 4M, will test the worst case bandwidth performance.

fio on the host with an empty disk image as target is how I would test it. The disk images can be found accessed directly on the host via /dev/zvol/{pool}/{image}.Doing it with direct and sync enabled and with a block size of 4M, will test the worst case bandwidth performance.
Looks like you didn't followed the best practices: https://pve.proxmox.com/wiki/Windows_2022_guest_best_practices
Your NIC isn't "virtio". Looks like your CPU type isn't set to "host", which would be recommended for way better performance when not running a cluster. Your are not using "virtio SCSI single" as disk controller. You are using two sockets but no NUMA.

Many thanks guys, I made an huge mistake configuring storage. Now it's working very well!
