Uhm, but the dd command wasn't :-) (the guest's root disk is sd2, not sd0...)
Now our numbers align much better:

Ok, so same per-core speed, so single-threaded performance should be the
same.
(Btw, you have 8 cores, not 4. 8 cores @ 4 threads each.)

Yeah, I was planning on using LDOMs as well. However, since I wanted to put
this into a datacenter (for a cheap price, so it not being the most curr

Another thing I noticed:

Hi!
I just installed OpenBSD 6.0 on my Sun Fire T1000 (with 2 SAS HDs in a
hardware RAID 1 that I set up from OpenBoot). However, I only get read rates
of less than 2 MB/s from sd1a (the softraid), but reads from sd0d (the
underlying partition of the softraid) get magnitudes more.
