You are going through amazing contortions to fabricate a number that's directly contradicted by _everything_. You're the hero of "evidence" and "academia" yet you prefer some stupid multiplication problem to data that was published by the creators of the machine itself. Hopefully you have more integrity when you're doing research. >said this was the theoretical _peak_ NPS for DB. PEAK. Not typical. I Your multiplication problem assumes that all of the processors are active and every single one is crunching a position that allows absolute maximum throughput. How many times do you think this has happened? I'm willing to bet "never." I'm much more willing to believe a PEAK rate of 555M NPS, which has actually been published somewhere.
