Hello! Thank you for reading my post! I'm creating my first Windows 11 VM on Proxmox and I was wondering what are the best settings for the storage? I want it to be fast so I'm looking for the settings that would provide the best performance. I'm using a DRAM-less SSD to store the disk of the...

I was wondering, why the "discard" option at Hard Disk isn't set by default. Can that cause negative effects or why it's not set by default?

My servers all run HGST260 enterprise PCIe NVMe drives, mirrored. The drives have great performance, but my guests seem to be limited by queue depth. Are we able to use emulated NVMe devices to increase the parallelization of disk IO, and would this help relative to the standard SCSI devices? I...

Hello, I am wondering if since we're using local ZFS for our VM storage, should we set all Hard Disks to "SSD emulation"? I know on Windows, this stops things like defrag from running, which kills CoW storage like ZFS. Does it do something similar on linux guests? Are there any other ZFS best...
