   Actually, take a closer look at your benchmarks.  Where SPARC falls 
down is floating-point performance.  The integer performance is quite 
good.  The FP performance has, historically, always sucked.

   Which, for me, is fine...because I have Machines (with a capital "M") 
which are *only* good for serious FP.
