Hi team, Just dropping some result of disk speed performance, if someone have some time, knowledge or any clues(maybe i did something wrong) to upgrade my freebsd 15 disk speed:
Proxmox - LVM-Thin - VM - CPU:2 MEMORY:2GB
- VM disk mounted with: VirtIO - iothread=1,ssd=1,discard=on
- My fio test
Proxmox - LVM-Thin - VM - CPU:2 MEMORY:2GB
