only 1-2 % slower then dd from /dev/dsk. Do you think this is general
32-bit problem, or specific to this combination of hardware?
I suspect that it's fairly generic, but more analysis will be necessary.
Finally, should I file a bug somewhere regarding prefetch, or is this
a known issue?
It may be related to 6469558, but yes please do file another bug report.
I'll have someone on the ZFS team take a look at it.
