And one would ameliorate transaction backlogs with....?
And 100tx/s? How does 210,000 transactions in a day equate to 100 tx/s? 86, 400 seconds in 24 hours, divide 210,100 by that number and it's much less than 100 tx/s. Maybe my math's wrong, but that sounds off.
Peak rate, not a rate that was maintained for an entire day.
What you're actually referring to is the peak backlog then.
1 MB (1,048,576 bytes), divided by 226 bytes for the minimum transaction size, then divide by 10 minutes, then by 60 seconds.... that'll be a maximum peak rate of, well whaddya know: ~ 7.733 tx/second.
Keep trying, eventually one of these arguments will stick.
