Hi,

Running OpenBSD 5.9 as domU on Xen 4.4 on DELL PowerEdge R410 with two SATA
disks in hardware RAID1 on the dom0.

Dell R720 and R620 servers, 10 gigabit Ethernet SAN, Dell MD3660i
storage array, 1.2 TB 10K RPM SAS disks in RAID6. I don't think there
is anything crappy or weird about the configuration. Test results for
CentOS on the same system: 170 MB/s write, 112 MB/s rewrite, 341 MB/s
read, 746 IOPS.
I'm assuming that there are others running OpenBSD on Xen, so I was
hoping that someone else could share either bonnie++ or even just dd
performance numbers. That would help us figure out if there really is
an anomaly in our setup.
