You have some mighty pools there. Something I find quite interesting is that those who have "mighty pools" generally obtain about the same data rate regardless of their relative degree of excessive "might". This causes me to believe that the Solaris kernel is throttling the read rate so that throwing more and faster hardware at the problem does not help.
