ok. So I cant make sense of this. I've done some testing running the intel Optane 900p 280gb ssd inside a windows 10 VM under proxmox 5.3-8 and I cant figure out why I'm only getting around 50MB 4K Q1 performance. bare metal performance should be closer to 200Mb/sec, one of the great benefits of running an optane drive is the performance at low Que depths.
I've tried the drive as a ZFS stripe of 1 drive. I've also trying making the pool as LVM. I also directly passed through the drive as a PCI device to the VM and interestingly I still got very similar results.
This system is a Supermicro X9SRL-F with a Xeon E5 1650 and 128GB 1333 Ram.
