Yaron,
  What version of Solaris are you running on the Thumper, update 8 is
significantly faster than say update 3?  Do you have any SSD's in the
thunper to handle L2ARC?

  What kind of performance are you getting?

  Have you tried a few tests like backing up Dev Random?  To see where
you're bottlenecking?
