Hello everyone. I'm new here. I have a Proxmox Server running an FreeBSD 13.0 instance, but I am facing a very low IOPS for the system. All disks are SSD, the ZFS pool is setup to mirror the 2 existing disks. I have tried to disable sync and change compression to LZ4. The IO delay goes extremely high. Also I have tried to setup a new Proxmox Server, with no RAID 1, but still the same way. Any ideas? Screenshots are attached. Also, I would like to know if ZFS uses all the available RAM of the system as cache, and for that reason its usage is always high, or if this is another problem with my server.
