Hi,
Here you are:

Okay, the virtualization-based disk benchmarks were so fun.
It would be more interesting to get an idea of how a quality SSD such as
how the Samsung PM953 / 850/950 PRO/EVO performs on various hardware
with OpenBSD running bare-metal.
So, if you have such a machine feel free to run "pkg_add bonnie++;
bonnie++ -u root" and share your results!
Also do "dd if=/dev/zero of=testfile bs=1M count=10000; dd if=testfile
of=/dev/null bs=1M" (that is 10GB).
Please do this both for all FS:es in "softdep", so we get a realistic
usecase - so first do: mount -A -o softdep -u
AND do it with all FS:es in "async", so we get some idea of theoretical
throughput: mount -A -o async -u
Afterwards switch FS:es back to normal by: mount -A -u
Thanks,
Tinker
