Hello all.
I just installed ovirt node and the hosted engine on a single host. As the setup did not
offer a option for local filesystems, I used a iscsi LUN on the same host. So the engine
got installed there. That LUN is a on a nvme disk, the kind that reads higher than 3GB/s.
Yet, on a vm, i cannot get more than 280MB/s. That's using virtio-scsi or virtio as
the interface. Using SATA gives around 350MB/s. I tested with dd, like:
Bechmarking writes: dd if=/dev/zero of=/root/test bs=1M count=7000 status=progress
Bechmarking reads: dd if=/root/test of=/dev/null bs=1M status=progress
Also with hdparm -t /dev/sda
Is ISCSI supposed to be this slow? Again, this is on the same machine.
