Hello,
I have setup 2 machines with FreeBSD 13, one with HDD 3-way RAD1 and one with NVMe 2-way RAID1, running as host with vm-bhyve. On each of 2 machines, I created guests running with Alpine Linux, then tested i/o disk with fio. It's strange that:
1- On guest machines, NVMe is just 1.5x faster HDD (4k random read/write 50/50: approx. 85-90 MB/s vs approx. 35-45 MB/s)
2- Using zvol dev type is slower than file dev type on NVMe host (4k random read/write 50/50: about 9-10 MB/s vs about 35-45 MB/s)
Please give me advices on using NVMe disks on FreeBSD 13 as host.
Thank you.
