+# Disk performance
+
+Taken from https://forum.proxmox.com/threads/virtio-scsi-vs-virtio-scsi-single.28426/
+
+> VirtIO SCSI vs VirtIO SCSI Single boils down to a simple architectural choice that has real performance implications:
+>
+> Standard VirtIO SCSI uses one controller that handles up to 16 disks, while Single dedicates one controller per disk. This matters most when using IOThreads (iothread=1), because threads work at the controller level.
+>
+> When using IOThreads, Single shows significantly better performance (often 30-50% improvement) because each disk gets its own dedicated processing thread. Without IOThreads, the performance difference is minimal (typically less than 5%).
+>
+> So the choice is straightforward:
+>
+> >   Want maximum disk performance? Use Single + iothread=1
+> >   Managing lots of disks with limited resources? Standard might be better to avoid thread overhead
+> >   From the VM's perspective, they work exactly the same
+>
+> This explains why benchmarks consistently show better I/O performance with Single + iothread=1, while keeping the underlying architectural differences clear.
+
+Which results in the following packer configuration :
+
+```hcl
+   ...
+   # VM Hard Disk Settings
+   scsi_controller = "virtio-scsi-single"
+
+   disks {
+     ...
+     io_thread      = true
+   }
+   ...
+```

+(Proxmox Clean Orphaned LVM)[https://community-scripts.github.io/ProxmoxVE/scripts?id=clean-orphaned-lvm]
+
+> This script helps Proxmox users identify and remove orphaned LVM volumes that are no longer associated with any VM or LXC container. It scans all LVM volumes, detects unused ones, and provides an interactive prompt to delete them safely. System-critical volumes like root, swap, and data are excluded to prevent accidental deletion.
