Right now, consensus consistently takes about 2 seconds (which is the minimum). In simulations, the consensus process increases with the log of the number of trusted validators. 100 validators brings it to about 3 seconds. 1,000 validators increases it to about 4 seconds. 10,000 increases it to about 5 seconds.
Based upon the latency we see in our network right now we *could* tune up the block production rate to handle 101 validators at 2 seconds. This would give complete confirmation in less than 102 seconds (51% of delegates signing).
I don't think there is much advantage to a 2 second vs 15 second block... but I am fairly certain that DPOS has proven it could scale better than Ripple.
Daniel, please reconsider your thread titles.
To answer your question: No, you haven't set any records - you are wondering out loud if you could do that, but you have not even attempted it.
Please reconsider your thread titles, they lead to elevated expectations that are rarely met.
