Okay, no matter how hard I try I just can't get the disk speeds to be remotely
reasonable on Indiana snv_91.
Here are the stats on the box in question:
SunOS web 5.11 snv_91 i86pc i386 i86pc
pci8086,346c, instance #0 (driver name: ahci)
disk, instance #0 (driver name: sd)
disk, instance #1 (driver name: sd)

Writing dd if=/dev/zero of=foo.bin count=55500 will write to disk from
1.1megs/sec to 3.3megs/sec *tops* I can't get the disk to write any faster. The
system I/O is just at a crawl.
Quad core xeon, 2 SATA 7200 RPM drivers / zfs root mirror.
I have detached the second drive and benched both of the drives, both come back
with slow results.
What could it possibly be? motherboard bug?

I hope this is enough information.
