Arrgg!  Bad advice, Amitabh.

You cannot extrapolate TPC-A numbers for one system by using another
system.  He'll have just as much luck trying to extrapolate TPC-A numbers
for the 3100-30 by using a different DBMS.  Or an RS-6000.  It just doesn't 
work that way.

Sorry to be so jumpy about it.  Just one of my pet peeves.
