AFAIR, Solaris express does install quite nicely on a dual Opteron machine.
IIRC, then it seems that one CPU does the bzip2 -d while the other one runs
the filesystem and the install process. I believe that my last installation
from DVD did take only a bit more than 30 minutes.
BTW: I get 6 MB/s from bzip2 -d on a 1600 Mhz Opteron. 2600 MHz Opteron should
give 10 MB/s.
