I personally think that the Hive chain throttles transactions. The reports from pablopenguin show a completely unnatural repeating spike/trough manner of how data is broadcasted. I'm just not sold then that this is a fast chain.
Because if ... IF Hive really is so superior, then why don't people at the wheel here put Hive through a STRESS TEST and report that data.. and even market Hive on that demonstration. See again, this is what makes me think it couldn't handle high throughput or else that's a very logical thing to do in order to step up and fill the void and to attract inventors.
I'm not clued on how all that backend works but the "3 second blocks" is celebrated simply because there's not much activity here compared to other chains. Or it's simply a falsehood.
