thanks.  all information's useful.
is there a place where the maximum and minimum hardware configurations 
for FC6 are documented?  what i'm really drive at is i want to know how 
many cpu's, 64 bit or 32 bit, how much memory, i can configure for my 
system.  is there any benchmark figures which shows how performance 
scales with more hardware on FC6?
