Rumor has it that Mike Cheponis may have mentioned these words: Now, let me use your analogy to prove that multiple independent busses are better than one single bus: Let's say in each of your cases, 1 of the weapons jams exactly halfway thru it's job... How much lead is delivered in each case? (1) 2MBullets/Sec: 1 Million bullets. (2) 1MBullets/Sec: 1.5 Million bullets. The multiple bus structure delivered more bullets with 1 bus still ready for work, whereas the single bus structure's work ground to a halt waiting for operator intervention. I hope to say that this is what others and myself have tried to convey. Hope this helps clear up my point, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.
