No, the tests are run sequentially. Write performance is measured first (20 MB/s), then rewrite (12 MB/s), then read (37 MB/s), then seeks (95 IOPS).
Okay, you are on a totally weird platform. Or, on an OK platform with a totally weird configuration.
Or on an OK platform and configuration with a totally weird underlying storage device.
Are you on a magnet disk, are you using a virtual block device or virtual SATA connection, or some legacy interface like IDE?
I get some feeling that your hardware + platform + configuration crappiness factor is fairly much through the ceiling.
Anyhow, run your installation on real hardware please, and make that (supported) hardware extremely good, and you should have nothing to worry about, given that your usecase is in line with OpenBSD's objectives per what Theo said.
Someone said SATA "multi-queueing" is not supported, I don't know any details including if it's correct and if such support is desirable. I have no idea about the NVME support and performance.
